Swaddling?

Rachel
I've been swaddling my 4-day-old son in muslin swaddling blankets, but he always breaks out of the wrap, and I get so tired re-wrapping knowing it's not going to stay. Any tips on getting a tight swaddle to stick?We have a couple swaddler sleeping products, but I get concerned about how close they come to his chin and whether they'll creep over his mouth during the night. :(
