Has anyone ever use this earmuff for baby? I'm tempted to buy, just thinking if he can sleep/rest better in crowded places (malls, outdoor)? Or should i just live without it?

I had something similar. Didn’t use it at the baby stage… too uncomfortable for sleeping. Tried to stick it on a sleeping baby but looked too uncomfortable. Could come in handy if the neighbours start reno works or something, but I’d say only for a toddler who can understand what the earmuffs are for.
