Get down on their level
Look them in the eye
Say in a calm, neutral voice, “It’s OK to be mad/frustrated/upset; it’s not OK to hit” (validating emotions)
Show empathy
Take note of which situations lead your child to hit others, and try to preempt them. Do they strike when they’re tired or hungry, when they’re feeling crowded, or when they have to leave a friend’s house? These are common triggers for kids.
Sidestep them with a little pre-planning: Make sure your toddler takes regular naps, keep snacks at the ready, and prepare them for transitions. Get creative when you plan ahead, too: If they lash out because they always want their playmate’s favorite toy, for example, ask if they can put the toy in question away before the next playdate.

We are the same 2.9 months and finally out of that faze

oh dear..time out!
2 minutes on a specific spot..If she slaps you.
respond firmly.
that hurts!
its not ok. slapping hurts.

If you see him , take his hand away and say NO to hitting . but do it all the time with consistency and soon he will get the message . May not be straight away , but he will learn .

Totally normal. Trust me, I’ve done a LOT of research and asked a LOT of professionals because my son is doing the same. The advice I’ve received is to have a consistent approach and continually remind them that hands are not for hitting. Not that my son is understanding more of what I say I also warn him that if he continues hitting then we will have to go home. Just be sure to follow through in the threat.
We’re still in the dreaded hitting stage but hopefully my consistency will pay off in the near future.

Keep being persistent and hopefully she stops

i would start on trying a naughty mat/corner she will start to understand that its not ok,you will have to be persistent though.

you need her to understand that it hurts! Ask her how she would feel? if it would hurt her! I sometimes tell my kids that santa know when they have been good or bad LOL and it works!

When this happened to me with my little boy I would pretend to cry and tell him that i was so sad and to leave me alone and it worked as he no longer thought it was a fun game.

I don’t agree to slapping back – they do learn by imitation after all and if you don’t want her to do it then why do it yourself. Put her in the naughty corner every time she slaps and tell her why. She will learn eventually.

My mother in law said my husband went through the same thing at 2 and she would cry when taking him to mothers group because not only would he hit but he would bite other children also. The paed told her that it was that he was having trouble trying to communicate and he was doing more out of frustration. She was encouraged to keep going to mothers group and every time he slapped or hit she had to remove him from the situation and tell he he couldn’t play if he was doing that. He soon learnt he had to speak instead of hitting or biting and grew out of it. I laugh about it now because my husband is the kindest, sweetest person and I could never picture him acting like that lol. It will be interesting to see if our daughter does the same thing at that age

slap her back on the hand and tell her no

I think it may just be a phase, kids like to push the limits, they dont know any better, just be firm and consistent!

create a little notty corner?

there are some good comments here

Take away toys or time out?

this is a hard one my daughter havnt done that yet

We had this as a massive problem recently! I was getting so fed up because nothing seemed to work.
I would say no baby hitting hurts, if you are going to hit mummy is going to walk away and if it happened again i would walk away, she usually wouldn’t do it again for the day because she enjoyed playing together. If it happened to other kids i would remove her from the situation for a little bit. I would also hold her hand and say gentle, no hitting. and make her do gentle movements with her hand.
If it was to do with something being taken away as a consequence, i would acknowledge her emotion “i know it upsets you that mummy is taking away your toy …”
But once i realised she wasn’t hitting to hurt, she was hitting to communicate that she was unhappy, i would try where possible to interpret the problem before she hit.
I was getting to my wits end and honestly beginning to become a little embarrassed. But our daughter barely did it for 2 months, she grew out of it on her own, once we helped her learn other ways to communicate. I read in so many different places that it is a stage they will grow out of, and they really do

Good luck

It’s just a means of communicating and I am sure she does not mean to harm anyone. Maybe establish a timeout corner?

I have found that saying “no slapping as it hurts” and If you slap again we go home or something she likes is taken away. The first couple of times she laughed or had an absolute fit. but then she understood I mean what I say. If you misbehave after I have warned you we leave the park etc. Being consistent helps. good luck
