He used to be fine in the cot, but now a nap in it doesn't last for more than 20 mins in it during the day ,that is if we can get him to go off in the cot at all whereas in a bed he will sleep for ages.At night if he's in the cot, once he wakes up at about 1 he won't go back to sleep unless it's in a bed, He doesn't seem to mind if there's someone in the bed with him or not. We have tried to cover the ends of the cot to avoid draughts, putting in toys, bits of our worn clothing (always worked with DS), bedding from our bed. We're doing co-sleeping and wouldn't mind but he spends a lot of the night pinching us on the face or body. Any suggestions welcome! Thanks.
