My childhood friend, seriously PG, offered classified jobs from her doctorate in nuclear engineering, only had the creative play thing with me. Her father was very strict about their schedules, doing science experiments. Not that it wasn't fun, but she mentions now, it wasn't balanced. She has a great career, refused to have chilren. Hard to have chilren and enter that world when you are so serious.
Wren,
I completely understand what you are saying and it is a concern. I too have a PG friend who has a little girl who is 14. Her PG Mom will admit that she has problems with the everyday life. When people comment on her intelligence she always says it is not exactly a gift and she would rather be a little less intelligent if it meant she could truly function in society. Her 14 year old has suffered too especially when her mom goes into serious depression and can't go to work or take her child to school or activities. I am not saying she is the norm for PG and I am sure she has some other issues beyond just being PG (not that PG is an issue) but I do know she was pushed as a child and never really had a fun childhood so you see her trying to overcompensate with her DD and put her into way too many activities and buy way more than she could afford.
