How much formula are you feeding your 4 week old? My son is getting 4-6 ounces evry 3-4 hours, and it just seems like a lot. He is gain weight normally and healthy. I just don't want to end up with a butterball!

Sounds like you are feeding him exactly right. and in a couple of months he will be eating 8 oz every 4-5 hours.

sounds normal. you should be feeding your FF baby just as you would a BF baby ... on deman and until full. and if it appears his eating is increasing, that is because there is a MAJOR growth spurt at 6wks. *wink*
