Napping alone

I know there are a lot of people saying their baby can only sleep when held....mine too and i am going nuts. He can be in a dead sleep and i put him down he wakes up....he sleeps fine at nightime but napping? No i have to sit pn the couch at all times i literally cannot do anything....so i am just wondering what everyone else is trying? What tricks are u using to help baby? My baby is super fussy and my husband is never around he works all the time i am getting super stressed out. I dont want to go far he can sleep right beside me i just need to move!
