When are we supposed to start saying no and enforcing rules for our babies ?

I started about a month ago (when he was 10 months) Typically safety things like when he tries to crawl on the dishwasher, go into our cabinets, etc and also when he tries to hit us or grabs our dog and I'll tell him no and to be gentle and show him what that looks like

Yes! That’s my main reasoning for starting cause she’s getting into everything!

I did the same.. started with telling her "no no" and giving a little finger wag lol now if she goes up to something she shouldn't she'll wave her finger sassily 😂

@Unity cute lol ❤️

Basically same as what’s already been said. Mainly just safety stuff rn. Tell him no when he’s doing something unsafe and then redirecting or moving him to a different location. But sometimes it’s for him actually being naughty. He’s started biting while I’m nursing so he gets told no for stuff like that. Or pulling his older brothers hair (I know he doesn’t really understand yet but his brother is 2 and always getting into stuff so it’s partially just to help even the playing field so he’s not upset that he’s always the one getting yelled at lol)

I start things stupid early before they even understand so it's seamless and it takes effect as soon as they comprehend I've been telling my girl no when she gets into things she shouldn't. I tell her not to pull sisters hair. She understands let go when she's got a death grip on my hair too

As early as 9 months babies can understand discipline according to research. So from 9 months I’ve been telling her no no and caca when she puts bad things in her mouth. I’ve recently implemented nice hands (due to my 10 month old having a 2 week old sibling now) but I would say when they start to recognize their name is when they can start to understand. Or when my 10 month old hits me I say “hands for hugging not hitting” if she continues after a redirect, I put her in her crib for a couple minutes after telling her no hitting. It’s seemed to work (never for longer than 5 minutes do I leave her in there except to sleep)

I started once he started crawling

We started during the newborn stage. Our tone/effort started out as general instructional and then shifted over time toward firm and expectant. He shocked us within the last few weeks by breaking down crying after being told no repeatedly when he kept touching something. Of course he still didn't have a full understanding because he reached out to touch it again while breaking down. (We hugged him and comforted him.) But now I'm trying to redirect the disciplinary messaging to apologies by encouraging him to hug and say sorry when we bonk someone on the face. He hasn't said his first word yet so it's just association building right now.
