My almost 3 year ( she will be in a week) is driving me insane. Ive been watching my niece and my daughter keep hitting her and when my niece have something my daughter wants it or wanna trade . Yes my niece does little bad things on the low but she is nothing like my kid. She is so quiet and sweet and doesn’t do much. My daughter is wild, she likes to run and play even after I tell her to sit down and makes a lot of noise. She doesn’t really listen neither she keep telling me no which I am trying to break her out off. I tell her to come here she says no or she say leave me alone. I am mentally exhausted her behavior Is making me wanna run away I just wanna cry . My niece is wonderful and my kid is like a baby demon. She is so hard headed but she also have manners and so sweet and giving and love hugs. I tried talking to her doctor about her behavior but she basically saying she just a toddler and it’s my parenting like idk how to be a mother this is my first and only child so I’m confused about that. I feel like she can have ADHD but she doesn’t jump off stop and her tantrums are regular she go throw things and flip something over when she is upset but it’s nothing serious. Is it screen time ? Like maybe I should stop letting her stay on the iPad ?
