Toddler help..

My two year old is totally crazy! She is 26 months for reference. I definitely need some guidance. I also have an 8 month old. But my 2 year old has terrible behavior. And now she has started hitting and punching and kicking, but only me. I’m trying everything to get her to stop. Everything. Can I see some schedules of moms with kids similar ages. Like what are you doing with your two year old during the day?? Maybe I’m not doing enough? I mean I try, like hell. Sometimes the baby needs extra attention. It’s tough. Please, advice, guidance, sample schedules? Thanks!!!
