My lo is 2 weeks old today. I thought she wasn't getting enough breast milk because she was nursing 3 times in 1 hour and a half, every 2 to 3 hours. I started her on formula last friday. Now she is doing the same thing on the formula. I would like to get her back to the breast since we have the same problem with formula. I nursed her several times over the past couple days and pumped some because It was so hard for me to give up on bfing. This is only tuesday and my milk supply has dropped drastically. How can I get it built back up?
