Was my response right when my two-year-old hit me?

[Waheymum]

Two year old got frustrated with me trying to help her with an activity (colouring in) this morning and hit me. I held her hand so she couldn't do it again and firmly said "no. We don't hit." I then took her out (with the baby as well) to the park so she was somewhere else doing something different.
She's my first child so I'm asking if I reacted correctly and if not, what should I do next time?

I don't think your wrong but I'm wondering why the child needed help colouring in? Just leave them to it and accept your walls might get a bit of crayon at that age. Better they learn to do it themselves you dont need to teach them colouring

Thanks. I did my degree in Fine Art so I was probably a bit over-enthusiastic, but my question was really about whether how I dealt with hitting was correct and whether I should have done anything else.

Did you immediately pack the colouring away and go to the park? Or was there a gap of her not knowing about the park?
It's correct to give a 'We don't hit' in the moment, it's important for them to learn how to handle frustration without hitting.
