Just wondered if anyone had any advice for me. I know it isn't a massive issue but I'm not sure what to do.
Ds2 is 18 mths and, generally speaking, sleeps through the night once he's gone to sleep he naps ok in the day and will fall asleep in the buggy or car easily enough. However, when putting him down for naps or proper bedtime on his cot he cries.
If I stay in the room with him he will lie there completely contented and drop off to sleep. Doesn't need any contact or attention (in fact it's what I'm doing as I type this), just goes to sleep.
Now, I suspect my mother would say I've made it a problem by 'giving in' and sitting in with him because know of course he expects it so if he cries I go back in and sit there. And I can't disagree that I do it because it is the easiest (quietest!) way to get him to sleep.
But just wondered what you'd do to break the cycle? It is quite a recent thing so he used to be able to get himself off to sleep - often he would have a little grumble as I shut the door but he'd still be asleep within say a few minutes and did not do the full on crying that he treats us to now!
Any advice gratefully received! 
Many thanks
