Re: when does breast milk fully come in?
Milk generally "comes in" 2-5 days after birth. Milk "coming in" refers to the changeover from clear, yellowish colostrum to whitish milk- if you see milk and are able to express milk, then your milk did come in.
During the first few weeks after birth, milk supply gets established, which means that a nice feedback loop is set up wherein the mom produces milk, the baby drinks it, and the mom produces more in about the right amount. Many moms get terrified thinking that if they don't establish a "good supply" within a few weeks of birth, then there's no hope for them, which just isn't true. Barring physical problems which inhibit milk production, your milk supply can increase at any time.
As the PP said, not getting much milk when pumping or hand-expressing is not an indication of poor supply, since a) not all moms respond well to the pump, b) not all pumps are equally good at removing milk, and c) the baby is much better at getting milk from the breast than the pump is. That being said, getting 2 oz when pumping- 1 oz from each side- is okay with a 2 week-old baby, who is probably drinking about that much at a feeding. And as the PP said, counting diapers is a much better way to judge milk input than pumping is: good diaper output = good milk input.
