Anyone else’s LO sleeping a TON?!?

Question

My son has been taking 3+ hour naps (normally 2 hrs) and sleeping 12+ hours at night again (he was sleeping 12 hrs for the longest time  but has only been sleeping 10.5-11 for the last month or two). 
So 15+ hours of sleep total? 
I think it may be the start of a growth spurt! He has also been unusually cranky lately and throwing way more tantrums/crying for NO reason.

Answer

UPDATE: 
In case if anyone else experiences this soon. 
All the sleep lasted 1.5-2 weeks. It was a definite growth spurt! He’s back to going to bed @ 8:30 and waking up 7-8AM. And napping 1-3PM.

Answer

my son has been doing exactly the same thing. 3 hour naps (which are usually 2) and sleeping 12+ hours. I can definitely tell a difference in his height.

Answer
