Need help !!

So my son is 1 month and a week old me and my bf was so in love with him when I first gave birth to him so we would always do skin to skin with him plus the doctors made us do it a few times while we was there and now my baby is super attached he always wants to lay with me in the bed. he doesn’t like when anyone holds him he always cry’s and when they hand him to me he’s fine and everytime he sleeps and I put him down he’ll sleep there for atleast 4 mins then he’ll cry and idk if its because he likes being on his stomach from me laying him on my chest or from me holding him but how can I get him to lay down without crying for me to hold him
