We welcomed our third child 4 weeks ago today. Our middle child turned 3 last week, and he is having a hard time sharing nursing time with his new baby sister. He asks to nuse frequently again (used to be just bedtime), and he makes up stories about "hurting" in order to get a chance to nurse. I am letting him nuse for a couple of minutes here and there, but I have low supply issues, so I have to be very careful about when I give him time to nuse. When I try to nurse both together, my son is very pushy with the baby. He even tries to pull her off the breast. I tandem nursed son1 and son2 with no problems at all. Any advice?
