I have had success keeping him awake in the car 9:20 or 9:30, but he still wants to sleep 2 hrs in the am.
It's only been two days, so obviously no change, but do you think I should cut down day time sleep and start waking him up from naps? maybe Limit total naps to 2hr (slowly), rather than the min 3 hr he wants? Hoping he transfers an hour to the night sleep?
He is only doing 13 hrs total sleep so I am loathe to do this incase he ends up with less.
