Sudden sleep issues

My formally fantastic sleeping 2yr old has started being difficult to get to sleep and has been waking during the night. Ds1 used to go to bed at 8pm with a bottle of milk and sleep through till 7.30-8am with no wake ups. He is also still having 1 day sleep in the afternoon of between 1.5-2hrs. The only time this varied was if he was sick.
In the last week he has started being quite difficult to get to bed, saying "no more go to sleep" and wanting one of us to snuggle with him. Then he will wake up at least once during the night saying the same thing and wanting to watch tv. Dh will then snuggle with him till he goes back to sleep. He will then wake up at about 6.30am. This means he is tired during the day and results in him either having 2 sleeps again or being incredibly grumpy.

Any suggestions as to why this might have happened and what we can do to stop it. It's killing me the last few nights with dh on night shift and ds2 still waking twice a night for a feed.

Has he got his two year molars yet? I found that when my girls started to get their molars, sleep was EXTREMELY disrupted until they came through. Other than that, I've got no advice except to struggle through. The great thing is, you know that he can sleep through, so he will eventually go back to that. He's just going through a tough sleep period. Our DD2 has started sleeping through again after a tough period that lasted five months (I don't mean to scare you but it can last that long). She was getting her two year molars. I'm talking waking up at least five times a night. Twice a night was a good one. There was nothing I could do except give her cuddles and help her through it. Now that they are through, she's sleeping through again. I knew she could do it, I just had to wait. Sorry if this post isn't much help. I just think that if they have been able to sleep through before, they will do it again, we just have to be patient unfortunately! sending you some sleepy vibes xx

PS there are other techniques you can try like controlled crying but that wasn't for us. I just couldn't do it. One because I hated hearing her cry, two because her cry is so loud it rattles my brain out of my head and three because it would wake DD1 up. I don't judge people who use it though. It does work for some people.

PPS we bought an amber teething necklace, which helped a little. Not a magic cure but it did help x

It might be him adjusting to the new baby. Maybe he has just realised that the bub is here to stay, and wants to check in with you guys at night.

He has been getting his molars so I figured that was probably it. It's not to bad normally cause dh gets up to him its just a paint when he's on night shift.

Yeah I figured best we could probably do was wait it out give him lots of cuddles and reassurance. Cc is not for us either. I hate hearing him cry like that and if it's got anything to do with ds2 I'd hate to make it worse by having him think we weren't coming for him.

Those molars are awful. I hope it doesn't take them too long to come through and when they do that everything goes back to normal for you and him xx

DS also suffered at that age with thos molars. It's a very likely culprit. Only thing is to ride it out best you can.
