guuuurl, my lil piggy wiggy(hehehe), is such a pig! i'm storing breast milk, and i'm bf'ing as much as i can, but i have been having to supplement my BM with formula! the only downside about formula, is sure they get full, but how do you know how much they had? so i guess realistically, i have NO idea how much alex eats! but sometimes he eats 4oz of formula, and will nurse for another 10-15 minutes(but only on 1 side)!
