I think hitting is never ok. At a baby group my daughter enthusiastically grabbed the puppets face. The lady running the class did a great thing, - she turned it into a game and showed her how to stroke the puppet gently. I'm trying that with her teddy's now, stroking the teddy and calling it "gentle hands". It might be a few months before she gets it but I will be starting now.
You are in PFB mode so this is revolutionary to you. All parents do the gentle hands thing.
There is no overthinking happening. It's a parent's job to model good behaviour.
Yes that's all you need to do. No need for discipline. Just model behaviour and redirect them otherwise. More complicated things come when they are older, not when they are infants.
I was hoping this thread would have led to some practical advice but apparently Mumsnetters are of the opinion that you just allow babies to be babies and just put your hair up. I think that approach underestimates their ability to learn even when they are tiny.
You're misrepresenting what people are saying. It's normal to have to change surroundings to suit a baby. Are you going to waste time in a cafe letting them learn about the steak knife when they grab it? Or are you going to say "no sharp" (or say nothing at all), move the knife away and distract them with something else.
Yes, sometimes you do just need to put your hair up. Babies gonna baby.
Good luck to you and your boundaries with the toddler years.
