Thank you so much ladies!!!
Ypu usually start producing colostrum which is pre milk an high in fat an nutrition which is what leaks while ur pregnant an then the actual milk comes in shortly after the babys born. Colostrum is what feeds baby till ur milk comes in. With my first son it took about 3 days or so b4 I got actual milk.
Can start as early as sixteen to twenty weeks but a lot of women don't produce until after delivery. Second or more time moms usually produce earlier because they've already done it.
