4 week old sleeping habits

Lu

Is it normal that my 4 week old still only sleeps 2-3 hours at a time (if I’m lucky!) in his basket. I thought he was doing pretty good as I was really struggling to get him to settle in his basket at all instead of on me, but then I read loads of posts on here about people’s babies sleeping 4,5,6 hours at a time!! I’m very jealous haha!
