I'm going to go for the obvious and basics. Because every new mom asks the question of "what do I need" so here you go.
1) crib: duh, but a bassinette isn't necessary. Just be sure you have the sheets and mattress protector too.
2) Diapers: lots and lots of diapers. For any one attending a babyshower, diapers are the most valuable present simply because you can't go without. You can live without anything else but diapers are a must!
3) Desitine/Butt Paste: that stuff is great and if used consistantly it will keep the rashes away. Vaseline works to prevent diaper rashes but if your baby already has one then the diaper rash cream works to heal it. And buy the good stuff, in this case its worth it!
4) Baby Swing once your baby starts cruzing off the blanket for "tummy time" a swing works perfectly so that you can do dishes/make dinner without your little one finding their way into the cupboards.
5) pacifires: even if you swear not to use one, if you have a colicky baby you will break down, I strongly suggest buying two or three different kinds because no matter what some babies are born with a prefrence. There's nothing you can do about it, believe me, I've tried!
6) Diaper Changing Mat: it doesn't have to be fancy, a simple mat with a waterproof backing works just fine. But you will need one because babies explode the second you take that diaper off! I suggest not getting the padding thing with sides. Its fun to look at but it creates more work.
7) Freezer Dinners: busy exhausted mom, hungry husband.... need I say more?!
8) Thin and Thick Receiving Blankets: depending on what time of year your baby will be born is what kind of blanket you will need, but almost all babies love to be swaddled. It creates a sense of security for their flailing arms and helps them sleep better. Learning to swaddle correctly will help you more than you realize!
9) Bottles: same with the pacifires you don't know what your baby will take to buy two or three so you know. Even if your planning to breastfeed for a year or so, you will still need it if you ever want to go on a date that first year!
10) Onsies/blanket sleepers: babies poop out of their diapers... I don't know how but in the first few weeks my babies all had at least two episodes f pooping OUT of their diaper and completely missing their diaper... their diaper looked like it was on right so I havee NO clue how this happened... lots of onsies and blanket sleepers came in handy!
There are the ever so basic
But if you have the money or know of a way to get one a breast pump (medela Electric) is something you will be eternally grateful for, especially in the first two or three weeks when your breasts are so full.
