FTM and my 7 week old only sleeps in a sling

So my baby will NOT sleep anywhere except a sling/wrap. Not even in my arms and obviously not in his crib/bassinet. I have to carry him in a sling all day. And also he prefers me walking. So I walk around my house for hours and hours. I’m really tired and I love him so much and I’m trying to be patient. Does this phase end soon? Will he eventually start sleeping in his bed?
