He has two naps a day of twenty minutes each. First is two hours after he wakes in the morning the second will be after lunch.
The problem is that within an hour of waking from the second nap he's exhausted again. I try my best to get him down again but he fights it until he's almost hysterical.
Consequently, for half of most days he's miserable. It also means he's exhausted by tea time and that becomes a battle.
His night time sleep is fine, wakes once or not at all.
How can I get him to have a proper nap?
