Baby wont sleep in bassinet

Hey mommies. So my LO is 6weeks old and wont sleep in his bassinet. I have done almost everything i can think of now its down to putting the poo emoji bean bag in his bassinet and laying him in that (he doesnt sink enough for it to swallow him) he sleeps in the bean bag just fine but i would really like for him to start sleeping in the bassinet that way it would be easier to transition to a crib. Please help
