He's obviously tired after being awake for 2-3 hours, but will only have one (long) nap a day. So if he wakes at 6.30am, he is tired by 9am, goes down for a nap until midday, then is awake until bedtime - 6.30pm! He's really tired but just won't nap.
If I keep him up til say midday, he'll have an afternoon nap midday - 3pm, which is better as he's not hysterically overtired by bedtime. But then he's tired all morning.
I've tried reducing the morning nap to an hour, and even 45 mins. Makes no difference. As long as he's had one nap in the day, he won't nap again.
At 6 months I though he should be having a small morning nap and a longer lunchtime nap.
Any help or advice please?
