Am I expecting too much of my 3 1/2 year old daughter?

Yeah,Parenting can be so frustrating. my little girl will be 4 in December and that sounds like her.she is the baby though.she is potty trained, but she does play in her food.She gets a rash from Ranch dressing.one thing i do know is that they grow up and grow out of that kind of thing,then you wish that they would just play in there food again.enjoy your baby.
