Hi Jessica. First of all, congratulations! That's exciting news. Do not worry that you do not have six weeks, it's ok. I would recommend stopping the birth control once you find out that you are adopting and start pumping right away. Once you get the baby take as much time as you can and just focus on breastfeeding, skin to skin contact, and having the baby at the breast as much as possible. The baby is the best at triggering your body to produce milk and your body will respond. You will want to pump afterwards. Keep us updated.
