So, our son loves to suck. Fortunately, this now includes the pacifier. Unfortunately, it won't stay in his mouth if he decides to pause and take a break. Instead of having to hover over him, waiting for the pacifier to slip out of his mouth, I made a him a head strap.
E says it puts him in the mind of Hannibal. We won't go out in public with it.
UPDATE: We stopped using it. It may be a good technical solution, apparently it is not a good medical one.
