I had the same with my LO and did exactly what you are doing. Don’t give her a reaction but keep the tone low when you say no and when you say kind hands (easier said than done… I cried a couple of times 🫣). She will eventually get it and will stop. I had nursery telling me she was a bit handsy but she’s stopped that too… she now gives kisses to the other kids x
My son doesn’t go to nursery but he picked up that behavior from one of the kids in a playdate. He was 15 months. I got on my knees to be closer to his face and I held his hands and told him very firm and “mad” that we don’t hit, hands are for caring and I pass his hands on my hair and on my face. He is now 17 months and never did it again. The toddler he plays with still hits toys and my son looks at me looking for a reaction and I just blow him a kiss 😂 My son never understands if I use “no” but he understands my mad voice because he doesn’t hear it that often.
My little boy does this sometimes as he thinks it’s funny, I’ve taught him gentle and showed him with my hand to stroke and not hit and he understands gentle now so if he hits I say gentle and he strokes, so has worked to a point but he does still hit sometimes…always in the face too 😂😂
Do you know why they are hitting ? Are they just trying thing s or responding to any sort of frustrations? If the second, then acknowledging the anger or frustration nay help. Eg. It is ok to be angry, but hitting is not. And try to give them alternative ways to express their anger. If it is out of curiosity, this is harder, and you may want to talk about how you feel and redirect. Mummy does not like being hit, it looks like you have a lot of energy, do you want to hit that pillow instead or jump up and down.
I think it’s an age thing, my almost 18 months hits too, persistence is key. Yous will get there x
