I've created a monster. My 3 month old went through multiple nursing strikes lately, and I coaxed her back to the breast by nursing in motion. Now, it's the only way she will eat. She won't let me sit down (even if I do so gradually, or keep rocking her like I'm walking) or even stand still. Help! I have neck and shoulder problems, so I can't keep doing this. Nursing her in a sling/carrier is also out; I have to get her to let me sit down.
