I had no idea what to register for either. I reached out to some of my friends and asked what are the must haves. Obviously, you need a carseat to bring your little one home in and essentials like a bassinett, onesizes (I was told best not to register for many clothes b/c folks will get you tons), a health kit with a thermometer etc, bottles, receiving blankets, bouncer, washcloths, bathing stuff..etc. I was also told the hospital sends you home with things too like formula. I am hoping to breastfeed but you never know. There is a checklist on babies r us but they list everything imaginable. I'm not sure about you but I don't want to put stuff on there just becasue...that means I will have to return things if I don't end up needing them...and people spend money that is hard to come by these days. Have fun with it...it is time to enjoy this!
