Morning,
For the first couple of days, I stayed in the room with DD while she settled. That way she's go in the cot and lie and comfort with her dummy and comforter and feel calm because I was there.
On day 3, I'd put her down whilst talking softly to her repeating the same thing over and over so that she'd eventually come to recognise that as the words to settle - I guess you could say anything you wanted but I said: "nap time, settle yourself, settle yourself". Once down in the cot, I would start moving out of the room slowly.
Invariably for the next few days, I'd get to the door or just beoynd and she'd start crying. It wouldn't always be the full on cry but more of a fake sort of "I'm going to cry if you leave" type thing.
I would return to the cot reassure her and keep on with the "naptime, settle yourself". and then leave the room again.
After lots and lots of back and forth, I'd get further and further from the room and down the stairs. But as soon as she would start with crying or even the fake I'm going to cry, I'd return immediately so that she would learn that I was listening to her and always always come back immediately.
Importantly, in the beginning even if she hadn't slept or slept much, I would pick her up when naptime was finished (ie after 45mins in the morning or after 2hrs over lunch).
As days passed, she wouldn't go for the all out wail but try some fake crying to get me back into the room and then smile at me. Annoying as it was, I just persisted and eachtime, I'd leave the room and make my way downstairs.
By the end of the first week, I would make it downstairs by 3rd or 4th attempt and she would start sleeping and taking the naps.
Bear in mind that I could then have total success with the morning nap and be really pleased only to fail with the lunchtime nap and she'd really play up.
And yes it was really frustrating for a couple of weeks and on days where she was really testing me and I would have a little cry and wonder whether I was a bad mother.
But each day I would win a little more. And after 2 weeks, she'd go for her morning nap and go straight down with no fuss and sleep at lunch time with only minimal fuss (me returning only a couple of times).
USERNAMEANGST,
I never ever left DD crying. I just couldn't do that. And by doing as above that never happened. And yes it seems like a lot of work now (and it can be) but unlike some of my friends with 1 year olds who wont nap and wail all the time with tiredness, DD naps with no fuss and she's a happy little camper.
Try staying in you DSs room for a few days while he settles or even thru the whole nap and then gradually try to leave the room.
Also with muslins and comforters, DD shoves everything in her mouth and her comforters are soggy after every nap. But if you're worried, get a cloth comforter from a shop which will be a little smaller and harder to get in the mouth.
If your DS cries as soon as you lay him in the cot, then hold him in the room for a while, and if you have a mobile turn it on, give DS his comforter/muslin and when he seems settled then try to put him down in the cot. And persist with it until you're able to lay him down and then you can start trying to leave the room.
If your DS will nap in his stroller then its much easier. My problem was the DD wouldn't nap in her stroller or car seat at all! Hence no choice but to go for the above.
