We also cosleep and I am 100% for it! Some parents aren't about it, but it might make your nights easier if you let him sleep with you for the next few weeks :)

He JUST transitioned from womb to world.. it's scary for him! Don't worry about spoiling him or anything. This WILL pass. It's very common for newborns to experience a "witching hour" in the evenings. It's a phase. Snuggle him up to you, hang in there mama. I promise it gets easier. Please don't ignore a screaming newborn though. Whether he's hungry or just wants to be close to mama, listen to him. All he needs right now is you. Congrats on the beautiful new baby!

Hmmm are his day and nights sorted. Maybe in the day he should have a separate napping zone for example a swing seat or moses basket or even take the chicco downstairs. And then at night have lights off, night zone and in chicco next to you. Also let him have his cuddles and clinginess at 7 and once he's asleep maybe transition him to the chicco?

he is in my room, He sleeps in a chicco next to me crib and sleeps in it fine all through the day but as soon as it's 7-8pm that's it he wants to cling to me and my partner he just screams and screams and screams solidly till we give in (we've tried ignoring him, giving him extra blanket, giving him scented things of ours..)
