Girls, I don't know what's happening with my baby. He's two months old and has been in the hospital since birth because he didn't latch onto the breast at all. On Thursday, we received the pneumococcal vaccine. Since Friday, my baby has been restless; sometimes he can lie peacefully, but then suddenly starts crying loudly. He's been passing gas less often and keeps arching his back like a worm. When I hold him facing me, he calms down. He also has a bowel movement every other day.
