My DS has just learnt to stand up holding onto furniture. I'm okay with that! But he's standing up in the cot when he's meant to be sleeping and howls his head off cos he can't sit back down. I apologise if this is a really really stupid question but how do I deal with this!! I put him down sleepy and then I think he realises he's in the cot, surrounded by 4 rails to hold onto and decides to stand up. Do they grow out of this or do I just keep persisting, going in, putting him back down etc. He doesn't get put in a sleeping bag for day sleeps. Keen to hear how others have tackled this. I'm just a bit clueless right now!
