Being restless

L

My son is 11mo and a week old. Lately he’s been very restless at night and often I end up having to bring him up to bed with me and most of the time he’s fine after that. Last night he woke up twice and the second time he was up for over an hour so probably until almost 4am, woke up at 7:30 but didn’t take a nap until sometime after 10 and was fighting it. And didn’t sleep for very long. Now he’s been laying down for his second nap which he also was fighting and ended up being restless again. So I laid down with him and he seems fine now and is back to sleep. Any idea why he’s being like this? Nothing has changed. He just had 3 teeth come in top laterals and one bottom, I don’t see anymore coming in. Is it just him growing? But don’t know why he’ll sleep better with me. Sorry I’m a ftm. Just want to know if there anything to try to get him to sleep through the night again. And possibly not fight his naps if he starts doing that to.
