My boy does this when he's way over tired. Our dr told us that at this age they tend to get tired but they struggle with FOMO so they fight the tired and stay awake longer. On high overstimulating days where he refuses his nap we typically let him take that late nap wake him up for maybe 2 hrs just long enough to eat and do our bedtime routine then back to bed, and he still sleeps throughout the night.
My son does it too. He hits himself so hard! But it’s a form of self soothing!
Yes, self soothing my baby girl only does it when she’s having a hard time falling asleep. That’s how I know to leave her alone so she can find a good sleep position and just knock out 🥲
Mine recently just started doing this too! I thought I was the only one confused about this 😅
Omg mine started this last week i literally had to pin his arms down! When I looked it up it said self soothing!
