T wakes up from most of his naps crying. He recovers but it makes me wonder if he's overtired? He wakes up at 6:30 /7 and starts his nap between 12:30 and 1 (though I usually put him down at 12:15 or 12:30). He goes to bed at 7:30/8.

Eta - he usually only sleeps 1.5 hours, which was the length of his morning nap as a baby.

Is this normal? As an infant he always woke up from naps happy and cooing.
