My lo is almost 2 and has been poorly with a cold for a couple of weeks - as a result of this he has been sleeping from 7pm - 7.30/8ish or sometimes even later. He is now recovered from the cold, sleeping 7pm-7.30am ish but isn't settling for his sleep at lunchtime. Obviously I'm not going to force him to have a sleep if he doesn't need it but he is shattered by 4ish and is getting overtired by bedtime. Also if we need to go out in the car at tea time he is straight to sleep then a nightmare to settle until much later in the evening. What do I do?
