Hitting. Need help!

Danielle • 25 years old. Engaged to the love of my life ❤️ Mommy to a beautiful three year old daughter, and expecting twins October 2020. 🙏🏼❤️

My daughter just started hitting out of no where 😩 it started when she was sick a couple weeks ago and now she hits every time she gets mad or upset, and sometimes just for no apparent reason. Idk what to do. I’ve tried telling her “No. Hitting is not okay!” I’ve tried just ignoring her. What did you ladies do when and if your toddlers were hitting. I’m afraid for play dates now 😑 thinking about trying time out but not sure if she’ll get the concept of it yet? She’s really smart and understands most things.
