C ongrats. So, I believe that this is your first little person. SO you will err on the side of caution. 7 days, at an average of one an hour, when he is awake, which isn't a lot, but you'll change it everytime that he wimpers, so about 56 diapers or 7 a day. Just FYI: If this was your second one: possibly 7 diapers for the week, you ignore him a lot more.
I will say 36, dont forget to place one over his faucet while he is being changed, signed, the voice of experience.
and make sure that they are finished before you change them! ( I got projectile pooped-on by my daughter!)
Don't believe anybody's guessed the lucky prime number of 29 yet. And congrats. Don't have any kids yet. shoot, I"m still one. Just a high school senior.
