Heeelllpp! 😩 sleep regression!

I mean where do I begin!!!!!!!! My lo is 18 weeks and I’m going to lose my damn mind! I thought waking every 2 hours when he was born was a big tough but this 4 month sleep regression is something else! He is waking just about every hour or less screaming. I either rock him right back to sleep or nurse him. But the second he touches his own mattress....we start all over again. He seems to stay asleep while on me, next to me or in my arms. I have no problem sharing my bed with him if that means we all can sleep. My husband is so against letting our lo sleep in bed with us because he doesn’t want him getting used to it. I totally get it. But mommy wants to sleep too!

What do/did you do to get through this?!
