Do some babies sleep a lot when they are teething? The past three days all my son has wanted to do is sleep. He has slept 12 hours straight the past three nights and has taken a couple long naps throughout the day. He’s always been a good sleeper but he’s never slept this much. He doesn’t seem sick, I’ve taken his temp and it’s been fine. He’s pretty happy when he’s awake but he’s more cranky than usual. He’s been chewing on everything for the past two months so I’m not sure what’s changed. Could he be getting a tooth?
