My son is very attached to me and we've semi coslept since he was born. Since he was 20 months and wanted his own room he's come in when he wakes.
For a long time if I settled him back in his bed he'd just wake half an hour or an hour later so I didn't bother. And then he began sleeping longer anyway, the odd regression here and there.
He began to sleep on all night if I took him back and settled him when he was about 3 and 4 months, but a summer of going away and then coming back to nursery etc has wobbled this! He's now two months off being 4.
What I don't get is why he will sleep all night (usually) at my parents house, (only goes I every few months) and when he goes away with his dad to my Pils. He's in the room with dad on a blow up bed and my mum sleeps in the same room as him at my parents. When he first went in his own just over 2 she slept in the bed with him, but since 3 he's been in his own.
But with me he's like a magnet! When I am away with everyone too he wants to climb in.
I'm absolutely fine with it (most of the time, occasionally his legs and arms flail!) and soak up the cuddles. But I don't really understand it.
I've tried being firmer and talking about it but it seems to make things worse. Always he's grown out of things when I've just gone with the flow.
I guess I'm just trying to understand the psychology!
