Have you looked at safe cosleeping? It's what we've done since birth because everyone gets the most sleep. Your baby doesn't even know they're a seperate person to you so it's quite scary for them not to have you really really close
ugh, that sounds super tough! it's totally normal for them to want to be close, but maybe try some skin-to-skin time in the bassinet or just keep trying to put him down when he’s in a deep sleep? hang in there, you got this! here's what the 'Heal App' says.... "It’s completely normal for a newborn to prefer being close to you, as they find comfort in your presence. To help your baby sleep in the bassinet, try placing it next to your bed so he can still sense you nearby. You might also consider gently rocking the bassinet or using a white noise machine to mimic the sounds he heard in the womb, which can be soothing for him. Additionally, try to establish a calming bedtime routine, like dimming the lights and softly singing or talking to him before placing him in the bassinet. Remember, it’s okay to take breaks and ask for help when you need it. How do you feel about trying these suggestions?
Have you tried many different types of swaddles? I’ve gone through a couple different ones with both kids. My daughter liked the ‘love 2 dream’ where her arms were up and my son like the ‘halo’ one where his arms are down. I’ve also used noise machines with both kids
