Won’t stay asleep

Im in the exact same boat right now. Hes been awake since 2:20 (its now 05:30)after a 2.5 hr sleep.
Ive tried putting him down awake but drowsy but after 10 minutes hes crying again. Ive tried letting him comfort suck but right now im so exhausted. Partner cant comfort him either and i cant sleep while he is trying as i can hear him crying 😭🤯
He will happily fall asleep on me though and i dont want to give in and co sleep as i cant sleep properly and im uncomfortable lying that way.
Sorry ive got no advice but nice to know were not alone. Sending hugs 🤗

Seems to be the 8 week sleep regression, we are similar at the moment. We had a fab routine, my daughter was so easy to put down and she would stay asleep 4-5 hours through the night. Now she is up every hour and only sleeps on me in the day. Unfortunately from what I've read, we just need to do whatever it takes to get through it... apparently week 10 should look brighter 🤞
It is so hard to stay positive with so little sleep, I am terrified I will fall asleep with her on me.
Good luck 🩷

Our nearly 7 weeks old does this too 😫 she only sleeps on us otherwise she is up after 30 mins 😭 the minute she’s awake she is so soo fussy and cries unless I feed her then she stops crying but moving around a lot with her hand pushing pulling but also cries if I take the bottle away 🙄 this things started at 5 weeks I’m so exhausted on an unknown level
