This sounds like the perfect situation - but I'm concerned. I haven't seen my 4 y/o SD show any anger or frustration since she was 2. Now, she only lives with us 50% of the time, but still... No tantrums. Ever. She has days where I sense she isn't happy, won't really look at you when she's playing, very chilly towards you - but still polite. It makes for an easy life, but is she keeping things suppressed? Is it that she can't express it? I hate to think she's keeping it all locked inside. She's a very confident girl, very bright. It just feels... off. Anyone else got or met a child that is similar?
