Help! I've been up the stairs 39 times in the last hour to lay DS back down in his cot after he has pulled to standing and then cries. Am I doing the right thing just to go in, say nothing, lay him down? He's 11 months. He did the same from 5-7am this morning only sleeping in bursts of 10 minutes. Please help, I think I am in for the night from hell. If this is the right thing to do how long/how many days will this take?!
