I can't anymore, my back is falling apart, my lower abdomen hurts, I can't put the baby down for hours. How do I get rid of rocking???? Is there a proven method? Sleep and breast seem to have separated, but rocking doesn't. He will lie down, then may stand up, play and cry because he wants to sleep.
