Ladies, what are the big things you bought for baby number two? Well have to buy another crib or get Henry a toddler bed and turn his bed back into a crib(it converts into a toddler bed). We still have a changing table that barely got used. We don't have a swing, Henry hated them so we gave ours to a friend. Henry never had a pack and play and we never needed one. I know a car seat, obviously, but are there any other things that would make life easier with two kids? Henry hated being stuck in a swing or stationary for too long unless he had plenty of space, so we threw out the bouncer we had since he tried to climb out of it. Will we need another? And what are the best second hand places to buy baby equipment that's good condition? I never feel right paying 300 bucks for something they only use for like 3 months. We have a once upon a child around here, so I'll check there often. Should I do baby wearing? And if so what do you recommend that's decently priced? And do the breastfeeding cover/carseat cover things really work? I'd love something dual purpose like that.
