Before your baby belly bump pops, you鈥檒l notice some other, um, parts getting bigger. That鈥檚 right; your always-an-A cups are suddenly overflowing. As you make your way toward聽labor,聽your boobs are likely swelling, aching and seemingly growing in Playmate proportions. Time to stash those tiny lacey bras (at least for now). If your mom friends didn鈥檛 tell you: During (and after) pregnancy you鈥檒l need to update your lingerie. You鈥檙e going to make a lot of mistakes as a new parent聽(don鈥檛 worry, your kids will still turn out just fine),聽but you should at least be comfortable in the right bra. These are the five styles you *need* as a pregnant woman and new mother.

1. The Maternity Bra:聽Sure, it鈥檚 totally tempting to run out and buy the next cup up in your regular bra. But the gentle lace design or silky stitching of your old standard isn鈥檛 likely to give you the support that you need now. Maternity bras are specially made for a pregnant mom鈥檚 growing breasts. They have thicker straps, added hooks/eyes and a softer lining. They offer support o鈥檖lenty, minus the uncomfortable underwire of your pre-baby bras.

When investing in one of these gems (they can be a bit pricey), have a pro measure you for the perfect聽fit (Victoria鈥檚 Secret and Nordstrom do this for free). Some of the best maternity bras聽will grow with you during pregnancy and also double as a nursing bra, like this Bravado Essential Embrace Nursing Bra ($49) or Hotmilk Chic Nursing Bra ($60).

2. The Sports Bra: Just because you鈥檙e pregnant doesn鈥檛 mean you鈥檝e totally given up exercise聽(unless you鈥檙e on bed rest, of course). But bounce-inducing movement plus common pregnancy breast tenderness mean you鈥檙e聽definitely feeling some discomfort鈥 if not a little pain. The extra support of a sports bra is what you need here. Not only will a sports bra stop the bounce, but it鈥檚 also made from fabric that keeps your now-sensitive skin sweat-free (or, at the very least, it wicks the moisture). Look for a high-impact model to keep your new assets in place, like the Cake Maternity Zest Flexi Wire High Impact Sports Bra ($80).

3. The Nursing Bra:聽You鈥檙e a new mommy and are all about nursing. Going braless isn鈥檛 exactly comfortable, but baby needs to eat! Not only do nursing bras provide the support that you鈥檙e craving, but they also have flaps over your cups that open down for easy access to your milk. Check out the Cake Maternity Parfait Lace Nursing Bra ($65) or the聽Anita Microfiber Underwire Nursing Bra聽($59). If you鈥檙e going to be pumping at all, a multitasking model with a hands-free breast pump function like this Simple Wishes Supermom Bra ($50) will be聽a Godsend.

4. The Sleep Bra: The days of tossing your bra off when the sun goes down are gone 鈥 for some new mommies, that is. If nighttime support is something that your changing body absolutely needs, a sleep bra is a must-have. These hold the girls in, while still being soft and completely comfortable. A wrap-style bra made especially for new moms, like this聽A Pea in the Pod聽Maternity Nursing Wrap Sleep Bra ($38) or a tank-style, like this Bali Comfort聽Revolution Bra ($15) will keep you feeling good聽while you snooze.

5. The Leak-Protector Bra: Technically, any bra can fill this category. You just gave birth, and now you鈥檙e trying to breastfeed. Your milk has come in and is apparently flowing freely 鈥 all over your shirt. There鈥檚 a fix for that. Absorbent breast or nursing pads sit in your bra and act as mini maxi pads for your nipples. They catch the extra leakage and keep your shirt safe from two tell-tale wet spots. A maternity bra or a bra聽that fits snuggly are best for holding these pads close to your skin.
