The Hotsling is all fun and games until someone (who shall remain nameless) blows out his (hint!hint!) diaper while in said Hotsling. Ew. Double Ew.
Updated to add: yes, you can machine wash the sling, and then air dry it over night. Also, accidents like this can be avoided if your mom is smart enough to realize that you are growing and maybe those newborn diapers aren’t cutting it anymore!
