Help 😓 my baby won’t fall asleep to anyone else besides me

What do I do? He is 6 months and will ONLY let me put him to sleep, my husband has tried, my sister, my mom... he will only fall asleep with me.

I can’t leave him with anyone because he is miserable to be around when he’s tired.

I need advice 😔

I should have added, we cosleep. I’m not ready to have him in his own room. We tried the CIO (a milder version, where you go in at 3 min, 5, 10, 15, don’t pick the baby up) but I couldn’t do it, after night 5 I had enough of hearing him cry.

I just want someone to be able to put him down for a nap
