My 8 month almost 9 month old has done nothing but cried for 3 days straight he's never happy I'm going to try to get him to the doctor today so see what they say but I just don't know why he's doing it he's generally a very happy baby but he's just started doing it. He's not running a fever none of his teeth look like they are trying to come in he's been fed changed rocked I gave him Tylenol and bought some teething drops gave him some of those just in case nothing soothes him he don't wanna play he don't wanna be held either he don't wanna lay down he acts like he's fighting sleep but does it even if he has had a nap. So I know he's not fighting sleep cause he's not sleepy. Idk what to do?
