I have a 10 month old daughter, developmentally she is 7 months (dixie), and babysit my 3 year old cousin (ava) 10 hours a day. She is an only child. Recently she has been taking my daughters toys from her. If my daughter is laying on the floor playing and talking, she will get in her face and yell shhhhh!! Yesterday she intentionally ripped a page from my daughters favorite book. She sits pretty much on top of dixie and will get mad and scream and cry if dixie starts kicking. She pees in the floor if I get on to her. She has unrolled an entire toilet paper roll into the floor. I have told her to stop, i put her in time out. I dont feel comfortably spanking her. I have told her parents but they continue to let her rule the roost at home so she thinks she can do it at my house too. I am just at my breaking point. I love her to death but my goodness!!
