What is your napping routine ?

My baby is almost 11 weeks old, he naps about 3 hours sometimes 4 I have to wake him up to feed and change diaper. He stays awake for about 45-90 minutes before he starts crying and wants to sleep more.

Sometimes he wakes up just to eat and goes back to sleep. Is he supposed to be sleeping this much? I let him nap as much as possible but like I said I wake him after few hours to change diaper and feed .

How are you ladies doing with your babies and their nap times ?
