I have noticed you and H spend so much time together considering you are not "together" right now....I imagine that is good and bad at times. For me anyway, I think I let expectations creep in when we spend a lot of time together.
Sorry about the concerns for D2. As an early childhood major, I feel it necessary to say that MOST 2 year olds don't know letters from numbers. And most find it hard to sit still and pay attention for more than a few minutes. I am sure she is a great little girl.
