How long are the naps

Dulce

So my son turned 16 months on the 20th and he has been waking up at 7 am and goes back to sleep at 9:30 -10 until 2 o’clock pm 🙀🙀 I mean I don’t mind since I’m 37 weeks pregnant I need that extra nap too but wondering if he is really hitting a growing spur or something is going on he is very active and sleeps through the night with the ocasional crying but I baby him and he goes back to sleep should I just let him sleep or call his doctor? Not at first time mom but first time this happens with one of my kids
