Baby sleep

Matt

Hey guys, new first time parent and just have a question. Everything my wife and I have been watching has said babies sleep 16ish hours a day. I feel like our baby boy doesn’t really do that. He’s 3 weeks old, is it something that’s gonna come with time? Also we haven’t tried putting him in his crib much to sleep as he refuses to stay asleep any we try. He usually just sleeps on the bed with us. Should we be trying with the crib asap?
