Yes but if they want to play around I think that’s fine as long as they know the actual word lol

We must use the right word/term ourselves and not confuse the child. Eg. Eat and not mam mam

I would correct. I appreciate when people correct me too. Nicely of course.

I never baby talked with my son. I just spoke straight English with him

Best to teach them from young, as it will help them with communications

I don’t correct them but point out that it is a word they made up

Always important to start young to learn the right things.

Of course, otherwise how will they know the correct one?

It depends on the context actually. But yes usually

Yes i do... better to let them know what is right
