Within an hour and a half of my new toddler being here she has put Kota in a head lock, spit milk every where including Keela’s face, hit Keke in the head with a wooden thing, bought broke my blinds, jumped on top of the girls while we were doing our flash cards, and threw Kota’s cars everywhere including at the girls.. she already been in time out (for hitting Keela) and I’m exhausted already. Idk how to get this child to listen. I’m trying to be very patient and understanding because I know she doesn’t get to be around other kids and I know this is all new but Keela (the three year old) is literally afraid to be away from me now. She’s literally right beside me and won’t even go play.
