He understands "Don't eat" because I say it to him if he cannot put things in his mouth on our walks or at the park - like rocks etc. ...
is this ok???
Am I supposed to say it sternly or just normal tone ... and redirect ... push hand away from his mouth?
He picks up everything and loves being down exploring ...
How old is he? Depending on his age, your reaction will be very different. My ds is only 7 months old and puts everything in his mouth. Completely natural and should be expected, but I don't let him keep things that are bad for him. I don't say anything, just redirect, give him something different and act really happy about it if he starts to tantrum. That's really all you can do at this age. I think scolding a baby is completely pointless, even if they did understand what you are saying.

Yeah, just a cheery but serious "bleh" or "we don't eat rocks!" or "yucky" or whatever - I would usually have to remove the thing from his hand (or mouth!) myself - and redirect. . My older son put everything in his mouth. He did stop at some normal age, and this was my approach.
