15 week sleep regression

Melissa • Proud mamma to baby boy 💙

I sit here in bed at 5am writing this ... with hope I’m not alone. My little guy is 15 weeks today and the last two nights he takes 30-60 min to be put down.. sleeps max 3 hrs and is up and takes another 30-60 min to go down and back up ever hour -two after that. For the last 2 hours he will only sleep in my arms.. even if he’s out cold , I lay him down and he’s wide awake crying. I’m exhausted! Is this an early start on 4 month sleep regression??
