My four year old is acting like a two year old

Ashley

 I don’t know what is going on with my four year old. She does great at daycare. She eats her food plays does everything right. The minute she comes home it turns into a total nightmare doesn’t want to eat throws huge temper tantrums. throws things at us tells us she hates us. Are we doing something wrong? What is the deal? She baby talks and thinks she is going to get attention that way. I don’t know what to do and it’s driving me insane. It’s been like this for about 3 months and I am at my wits end. First time mom here so any help would be beyond helpful.
