Discipling a toddler

Mandie
Hey guys! I have a two and a half year old who I could use a few tips with. She's such a sweetheart and the light of my life. I'd really love to broaden my horizons on discipling tactics. Recently, she's gotten pretty naughty... kicking, hitting, spitting, screaming. And the worst part of it, for me, is when I ask her to stop she'll do it over and over. She'll smile the whole time too! Right now, when these things happen, I'll get on her level and tell her not to do these things and why. Then when she continues its time out for 2 minutes. I'd love some other ideas. We also have a one year old, so I really just want to keep everyone safe and happy. I'd love to hear from anyone with any ideas or experiences! Thank you!
