This is a strange one!
The last week or so I've noticed DS will stop and lie down when playing. He'll be walking around, then just stop and lie for a bit then get up and carry on. Sometimes he'll do it when trying to pick something up and give up and have a rest. He also comes for cuddles more and will rest his head on my shoulder.
He's been sleeping pretty badly - has a cold, teething and I've gone back to work. So in the night he can be awake for an hour crying and he's waking early in the mornings. So is losing sleep.
Could the lying down thing be because he's tired? Am I being silly - I'm not worried (yet), it's just so out of character. He's also been crawling more, despite walking for a couple of months now.
