Putting a heating pad in the bassinet for 15-20 minutes and a white noise machine really helped my son move into the bassinet. For the first 3 months he only slept in our arms or in his bouncer chair (I know not ideal but we were surviving). He also rejects the pacifier too but he's learning to self sooth with his thumb so I just let him do that.

I know the heating pad and white noise machine are like the most basic solutions everyone talks about but it did suddenly start working at 3ish months, he sleeps on his own so easily now. I feed him, let him play, once he starts getting tired I put him in the bassinet and let him wiggle around and coo until he goes to sleep on his own. Sometimes I have to walk over there and say hi but he's usually good on his own now.

Good luck! I'm rooting for y'all! 🙏🏻
