Just in the past week DS has started playing up when put in his cot to go to sleep. Full on screaming. Last night I gave in and took him to my bed to lie with him and get him off to sleep. But I wont be doing him any favours long term will i? He's crying now, having just woken up, did not want milk. Took about an hour to settle earlier. Stops as soon as I pick him up but out and out screams when I turn my back to leave. I wonder if it is related to me going back to work and if I should be a bit softer with him? He's nearly 8 months.
