5 week old noisy

My 5 week old is always noisy in his Moses basket to the point I can’t get to sleep but when I put him in the bed with me he’s quiet and sleeps properly. He’ll wake up for a boob as he’s breastfed in which we both fall back to sleep. Why is he noisy in his crib but not in the bed? Can anyone help or give tips? I already share my bed with my 3 year old and I end up on the edge by the morning

Yes I’m aware of dangers which is why I need tips - My 3 year old stays on his own side and pillow and doesn’t come over to mine but I don’t want to be bed sharing with 2 children.
