Aww first time mommy ka pa lang, that's exciting stage na yan! At 1 year 5 months, consistency lang talaga ang key, set simple rules like "no hitting" or "sit when eating" at apply it every single time, kasi ngayon pa lang sila natututo ng boundaries. A few of us moms agree na it's not really about punishment yet, more on redirecting, kapag gumagalaw siya sa dangerous place, gently move her away at say "no" with a calm voice, then distract with something better. Patience talaga, kasi they're still so small at hindi pa fully nakakaintindi, pero matututo sila with repetition, my toddler took weeks before naintindihan naming di pwedeng abutin ang stove hehe. Be kind sa sarili mo na rin, first time mommy journey mo pa, you're doing great!
