Any other 9 month olds suddenly not sleeping through the night ??? My guy has always been a decent sleep but the last few weeks he has been waking up several times hysterical and unable to put himself back to sleep. He was a thumb sucker and now that he got teeth he won't suck his thumb or take a pacifier so he needs to be rocked but it's getting to be a lot and Idk how to help him do it on is own with his thumb really. I also don't know why he's waking so much ( yes could be teething but he did not do this with his other teeth )
