My newest 4 year old is a MASTER manipulator.
Today my three girls were taking turns playing with 2 doll highchairs. When I said "In a couple minutes it will be time to trade" she handed one of the girls her highchair in hopes that when I said "It's time to trade" she would then get the highchair back again for another long turn.
If she has something and I tell one of the other girls "I will go look for another one for you" she will all but throw the one she has at them so she can get the one I am going to go find because she knows she will want that one.
She watches every move me and my husband make. As soon as we turn our backs she will do something she knows she would get in trouble for if we were watching.
That being said...
A week or two ago, when she was in trouble, I asked her if she was upset about her bio parents. She said yes. I felt bad so I let her off.
Now every time she is in trouble she says the same thing, "I want to go play at *insert bio family's names here* house". She seriously does not remember her bio mom. The only reason she knows her name is because I told her what her name was. She does remember her bio dad, but I don't know to what extent. She never talked about them at her old foster home. I do think she likes talking about them so I will continue to let her, but I think she is playing me when it comes to her being in trouble and bringing it up.
