My 18 mo DS is tall and has nearly toppled out of his cot, so we have taken the side off. He used to be a really good sleeper, would get into the cot, snuggle down and sleep all night. Since we have taken the side off he seems upset, gets straight out and follows us to the door, wails and cries on the other side of the door. We go in, pick him up, cuddle and say sleepy time, put him back and leave again. he gets up again.... first night it took 1.5 hours, second night 1 hour 20 mins. should we persevere or is he too young?
Any helpful tips - the most difficult bit is that he seems so upset being left, having previously been happy to settle himself.
