Thanks! we have put a bed guard on, but JT can wriggle out the bottom of the bed. We were in our lounge yesterday after we had put him to bed and thought he had gone off to sleep, only to discover him cuddling the dog! He crawled towards us with the cutest expression - a mix of being very pleased with himself and knowing that he shouldn't be there. It was such a struggle not to laugh at him, scoop him up and give him a big cuddle. It was quite a struggle to get him back to sleep.
Tonight I've been reading him stories, trying to contain him in bed and going over the events of the day until he is really, really calm before I left the room. He kept getting up at first & wouldn't lie down, so I ignored him when he stood up and continued reading when he lay back down.
It seems to be working at the moment......
