1 year old girl screaming?

Gina seems to be a little spoiled, ok alot spoiled. she is probably the only child and doesnt really get the "interacting " thing down packed. When first stated you said your daughter, loves to touch and pull and tug on her...well that may have set it off. Try playing games with the both of them at the same time to get them to positively interact with one another. Simple games, p a ball to one another....watch the cartoons that have singing and dancing. Help them help you. Good luck
