I have a friend who is ff her dd. I am bf my 11 wk old ds, who at 11w is 2 wks older. Basically when I see my friend giving her baby bottles of 7oz I can't help but wonder how or if my ds is getting enough milk as there is NO WAY that amount of milk comes out of me at each feed. My ds sucks for up to 45 mins at a time I don't want him to have to work hard for his feeds if he's not getting enough I know people say you never run out but am I enough for him?
