As you begin to plan and prepare for your babies’ arrival, one of the most fun milestones ahead is your twin baby shower. Not only is it a chance to celebrate your journey and the babies you’re eagerly waiting for, but it’s also the perfect opportunity to gather all the essentials you’ll need for life with two little ones.
In this post, we’ll cover all things baby shower for twins, from coming up with a theme and inspiration for decorations and games to staying comfortable during the event. Plus, we’ll talk about a few common pregnancy symptoms you might be experiencing right now.

How are you feeling mama?
Twin Pregnancy Symptoms at 21 Weeks
Common Skin Changes in Twin Pregnancy
At 21 weeks, your belly is expanding quickly to accommodate your twins, and you might be starting to experience a few niggles and changes to your skin. You might experience stretch marks, especially on your abdomen, breasts, and thighs. Moisturizing regularly with products containing cocoa butter or shea butter can help your skin stay supple, though genetics play a big role in whether or not you’ll get them.
In addition to stretch marks, some moms of twins develop dry or itchy skin due to hormonal changes. Hydration is key, so make sure to drink plenty of water and apply a gentle, fragrance-free lotion to soothe any irritation.
You may also start to notice darkening of the skin in areas like the neck, underarms, or around the belly button—this is known as hyperpigmentation and is completely normal. It usually fades after delivery.
You may start to notice a darkening line from your belly button to your pubic area. This is called a Linea Nigra and often starts to show around about now. An increase in hormones causes this darkened line of pigmentation and will disappear after your babies arrive.
Varicose Veins
Varicose veins can also start to make an appearance around Week 21, especially in a twin pregnancy. The increased blood volume, combined with the pressure from your growing uterus, can cause veins in your legs to swell and become more visible. While they can be uncomfortable, wearing compression stockings and elevating your legs when sitting can help improve circulation and reduce the appearance of varicose veins. Staying active with gentle exercise, like walking, can also support blood flow.
What are your twins up to this week?
Your Twins at 21 Weeks – Height & Weight
At 21 weeks, your twins are each about 10.5 inches (26.7 cm) long, from head to toe, and they weigh around 12.7 ounces (360 grams). To give you a visual, each baby is about the size of a large carrot or a banana. Remember, if you’re carrying fraternal twins, there may be slight differences in size between the two, which is completely normal.
Your Twins’ Fetal Development at 21 Weeks
Your babies’ movements are becoming more coordinated, and you might even notice distinct patterns in their activity. By now, their eyelids and eyebrows are fully formed, and their hair follicles are developing on their sweet little heads. However, you won’t be able to predict their final hair color just yet!
They are also developing their sense of touch. By Week 21, their nerve endings in the skin are developed enough for them to start feeling sensations. They may start to touch their own faces, grab the umbilical cord, or even bump into each other! This development of tactile sensation is a major milestone in their sensory growth, helping them learn more about their surroundings within the womb.
Your babies’ taste buds are fully formed by this point, and they’re starting to taste the amniotic fluid they’re surrounded by. Since the amniotic fluid takes on flavors from the food you eat, your twins are getting tiny “previews” of different tastes, which may help shape their preferences after birth. If you’ve been craving sweet or spicy foods, your babies are getting a hint of those flavors too!
Your twins’ hearts are beating strong, and their circulatory systems are now fully operational, circulating blood throughout their growing bodies. You may have already heard their heartbeats during your prenatal visits, but at this stage, their hearts are growing stronger every day. Their heart rates may fluctuate based on their activity levels, and if you’re lucky enough to catch them on an ultrasound, you might even see their hearts pumping in action!
Another exciting development is your babies’ immune system. At 21 weeks, they’re starting to produce white blood cells, which will play a key role in fighting off infections after birth. Though their immune systems are still immature and won’t fully develop until after they’re born, the foundation is being laid now to help keep them healthy.
What You Might Be Wondering About This Week
Planning Your Twin Baby Shower
Planning a baby shower is always a special time, but when you’re expecting twins, it’s a double celebration!
Your twin baby shower is the perfect opportunity to gather with loved ones and prepare for the arrival of your little duo. Whether you’re keeping things simple or going all out with a twin-themed extravaganza, this special event is all about embracing the joy of expecting two babies.
From must-have gifts to fun games with a twin twist, let’s help you plan a memorable day that you will be able to look back on with fond memories.
Planning a Twin-Themed Baby Shower
Planning a twin baby shower can be double the fun, but it also requires a bit more organization to ensure everything runs smoothly. With two babies on the way, it’s a special celebration that deserves its own unique touches.
Here are some tips on how to plan a twin-themed baby shower, along with practical advice on what to plan for to make it a memorable day for you and your guests.
Choose a Fun Twin Theme
When it comes to a twin-themed baby shower, you have the chance to get creative! Picking a theme that celebrates the excitement of having two babies can add an extra layer of fun to your shower.
Popular twin themes include:
Two Peas in a Pod: Use green décor and cute “pea pod” references in the invitations, cake, and decorations.
Double the Love: Focus on hearts, love, and romance, playing up the idea that your heart has room for two!
Thing 1 and Thing 2: For a playful Dr. Seuss theme, use bright colors and whimsical decorations to celebrate the adventure ahead.
Twinkle, Twinkle, Little Stars (x2): Perfect for a more elegant shower, with starry decorations in gold, silver, or pastel tones.
The key is to find a theme that you love, and that reflects your style and personality.
Invitations: Let Guests Know It’s Double the Fun!
When creating your invitations, make sure to emphasize the twin aspect! Whether you’re going with a cute or classic theme, mention the exciting news that you’re expecting twins right on the invite.
You can choose phrases like “Twice the joy, twice the love—join us to celebrate the twins on the way!” or “Double the diapers, double the fun—let’s get ready for two little ones!”
Etsy is a great place to find inspiration for invites, and you can purchase templates there to save time or if your design skills aren’t one of your strengths.
Decorations: Double the Details
For a twin baby shower, consider decorations that reflect the theme while playing with the idea of “twos.” Here are some decoration tips to get you started:
Pair everything: Use two cakes, double sets of balloons, or matching centerpieces. This reinforces the twin theme and adds a cohesive touch.
Use twin symbols: Think about incorporating cute pairs like ducks, baby booties, or teddy bears. You can also hang banners that read “Twins on the Way!” or include matching decor elements in your color scheme.
Photo areas: Create a fun photo booth or backdrop where guests can take pictures. Consider props like “Mom of Twins” signs, baby rattles, and onesies for a memorable keepsake.

Guest List and Invitations: Plan for Extra Guests
When planning a twin baby shower, your guest list might grow larger than it would for a singleton pregnancy. Friends, family, and coworkers might all want to celebrate with you! Make sure you choose a venue that can comfortably accommodate everyone, whether it’s a cozy backyard gathering or a rented hall for a larger group. Consider offering a virtual option for guests who may not be able to attend in person but still want to be part of the celebration.
Food and Cake: Two is Better Than One!
For the food, have fun playing off the twin theme! You could create a “Double Delight” buffet with paired appetizers and snacks. Consider serving two cakes or cupcakes in two different flavors—one for each baby.
Alternatively, create a cake with two tiers, each representing one twin, or feature a “pea pod” cake with two little babies nestled inside. Keep the menu light and simple, offering a variety of finger foods that are easy to enjoy while mingling.
Don’t Forget About Timing
With a twin pregnancy, babies may arrive earlier than expected, so it’s a good idea to host your shower a little earlier than you might for a singleton pregnancy.
Many twin moms have their showers between weeks 24-28, giving you plenty of time to celebrate before entering the later (and more physically demanding) stages of pregnancy.
It also helps to have a bit of time to work out any gaps you may have in baby gear after your baby shower so you can make a plan to purchase them before your babies arrive.
Delegate Tasks to Make It Stress-Free
Carrying twins means you’ve got a lot going on, and the last thing you need is added stress from planning a big event. Delegate tasks to friends or family members so you don’t have to handle everything yourself. For example, someone can be in charge of decorations, another person can coordinate the food, and someone else can handle RSVPs and games. This way, you can focus on enjoying the day without worrying about the details.
Plan for Comfort
A twin baby shower can be exciting but also tiring for you, especially at 21 weeks or beyond. Make sure you plan for your own comfort during the shower:
Have a comfortable chair or space where you can sit down and relax.
Plan the shower for a time when you typically feel your best, avoiding early mornings or late afternoons when fatigue might hit harder.
Plan plenty of snack and hydration breaks to keep you feeling energized.
By planning ahead and incorporating these thoughtful touches, your twin baby shower will not only be fun but also an experience that you can enjoy comfortably.
Final Thoughts
Your twin baby shower is such a special event, filled with love, laughter, and anticipation. I LOVED my twin baby shower as it was a chance to celebrate with friends and family who were also excited to meet my girls.
Whether you go all out with a twin theme or keep it simple and sweet, the most important part is to enjoy every moment, remember to stay comfortable, and take in all the support and excitement from your loved ones.
You’ve got double the reason to celebrate, and we’re cheering you on every step of the way!
