Lately my two and a half year old simply will not get in his cot when he's awake. He'll scream and cry before he's even in it. If I put him in and simply leave him, he'll scream and cry until we get him out. Left him up to three hours one night and he did not stop screaming. We have to lie on the floor with him until he falls asleep and then lift him in. He's fine when he wakes in the morning, and he sleeps right through. As you can imagine, lying on the floor is doing my back in a bit, as we are sometimes there for a couple of hours.
We did move in April, before that he was fine about getting in his cot. When we moved he got his own bedroom, he was fine getting in his cot for the first few weeks, but then suddenly one night he woke crying and it's been as mentioned above since. I'm not really sure what to do as all advice says get him in, wait til he's settled and go, but he won't even settle. My partner thinks it might help to only have one of us in there at night, but I know exactly how that will go, it will be me every night, he will make excuses, insist I need to do it more often as he works late, and I'll have no free time for myself. So I'm reluctant to do that.
