Paula,
My son is 4.5 months old and he is a big guy! He wears size 3 huggies and I like them the best! We got them at the hospital and I have tried others, only Huggies seem to make it through the night, I get the Gentle Care Huggies and they do great for him. If you sign up online for coupons, they send you a bunch throughout the year.
Good luck!
S.
