Interested to hear any thoughts or from people with similar experiences.
DS is almost 11mo, not a good sleeper ever since 4mo sleep regression. He has never slept all night, at best six hours in one go and that only a handful of times 
A good night would be 2-3 wakeups, a bad night 5-6. We've had weeks of bad nights lately as he's finally got his first tooth.
His cot is in our room and he's been in it at nights since birth and for daytime naps since about 4.5 months. Daytime naps are mostly ok. He fights going down but once asleep, gets a couple of good ones in (say 1h15 in morning, another hour in afternoon). He goes down around 7-7.15 and stays there till we go to bed, sometimes needs resettling. However, after we go to bed, if he wakes up in the night he can be extremely difficult to resettle in the cot. It started about 8.5mo as he was cracking crawling and has continued ever since with pulling up and especially the last bout of teething where he's been in a lot of pain even with Calpol. For months he's been coming into our bed from midnight to 2am ish, as otherwise he wakes up every ten bloody minutes.
Yet he's fine the first part of the night and we can resettle him - so I'm wondering if it's because he can see us and knows were right next to him. Is it time to bite the bullet and move him? I'm dreading going to and fro to another room in the middle of the night and we'd miss him 
but is it time? Has anyone else had this and it helped?
The other issue is that he's a very alert and curious baby, and if there's anything at all interesting going on in his environment then sleep is a no. That apparently includes his cot as he can pull up in that - endless fun. We have to cuddle/ jiggle him until he's completely asleep otherwise every lay down, even if very drowsy, he'll just sit straight back up and then pull up. I have lain him back down literally dozens of times - he thinks it's a game. Needless to say, I can't be bothered with that at 2am. But he's getting so heavy I know we need to work on getting him to settle himself - just don't know where to begin!
Apologies for the long post.
