When do babies learn not to put things in their mouth?

My 10 months old tries to put everything in her mouth😩 When do they learn that it is not okay to do so?

Probably not until they're at least 3 I think x

Ive been asking the sameeee But i think its a couple years yet

Mine still does at 17 mo, but much less though. He analyses every object he holds and when he ‘thinks’ it’s edible, it’s going in.

Mine stopped by about a year I think

@Thalie that would be so nice

@Alina exactly the same!!
