Diaper help..........?

My son stayed in size two the longest so far. Now we're in size 2-3 of pampers swaddlers. I wouldn't stock up on too many before he's born. You never know what is going to work for him. My son got diaper rash from huggies and always leaked in Luvs. Other babies are different. You don't want to stock up on a certain brand only to find out that they don't work with your baby. I know that it is tempting to have it all ready, but you could end up wasting a lot of money on diapers that don't work for your baby. Good luck!!
