I'm at my wits end. Over the last few weeks (from 4 and a half months) my 5 month old DS has become increasingly resistive to napping during the day. I'm writing this after half an hour spent trying to help him settle in his travel cot for a nap. He's screamed so much that he's made himself retch despite me being there next to him, shhing/ patting etc. He's eventually fallen asleep on my shoulder. I know I can put him down now that he's actually already asleep but it's far from an ideal situation. In face even getting him to fall asleep on my shoulder is becoming increasingly difficult. He thrashes about and cries and I have to really work to get him to relax.
I'm really at a point where I can't see the wood from the trees. I don't know what I should be doing to improve the situation.
He isn't like this at night - he isn't a great sleeper but can be put down awake and will quickly settle himself to sleep. He'll also self settle quickly after nighttime feeds. He has a very solid night time routine so I don't know whether I should be introducing a daytime nap routine? He also sleeps really well in the car and out about in the pram.
Please someone give me some pointers as I'm starting to really dread days in the house seeing him get so worked up and upset. I feel as though I've gone seriously wrong along the way somewhere
