My LO is one week old. She is gainging weight and seems very content, so I'm sure she is getting enough milk, but nursing is very painful because she is not latching on correctly. Her little neck is so strong, so it seems like the only position that works is cross cradle so I can hold her head still. Otherwise she turns it and thrashes all over the place. She also will not keep her hands out of the way. It seems like every time I finally get her to open wide enough she shoves her hand into her mouth. It's really hard to hold both hands when one of my hands is holding her neck. When I finally do get her to open wide enough it seems like she always slides down onto the nipple. I'm pretty large breasted so I'm afraid the shape of my breast is just too akward for her, and I don't want to have to sandwich my breast constantly. What do I do?
