This seems like a new thing because when we were kids you just went to bed.. you didn't get cuddled to sleep. And you didn't wake up every night and go into your mum and dad's room! Occasional nightmares aside.
But it seems vastly common from what I've heard that kids just do not stay in their own rooms and I just don't get what's different? I didn't do anything my mum and dad didn't and I had no problem just going to bed and staying there but my son is 5 and constantly wakes up - every night without fail. When I was aware I would take him back repeatedly to his room. Sometimes he went straight back off and sometimes I had to repeat it a few times. But now he's like a night ninja he slips into my bed without me knowing and i wake to find him fast asleep between us! I have talked to him, we've done pompom jar incentives. He just isn't getting it and he's not sleeping great and neither are we, but what else can I do? He'll go to sleep fine but without fail will at some point get in with me and I'm unaware until I wake up at 4 or 5 with a knee in my back. And by then it's nearly time to get up anyway.
Talking to family and friends with young kids this seems so common and we can't find a common denominator. Someone suggested weighted blankets and duvets but we've tried different mattresses and pillows and duvets it doesn't seem to make a difference so I'm loathed to buy more bedding if that's not going to do anything.
Anyone able to share? Or have a winge of their own :/
