To some degree, every parent gives up a large portion of their lives for their child. That's just parenthood. I haven't ranked first in my own life since 1985.
However, that's not the same thing as focusing everything on my kid's career. I wouldn't do that. It's not healthy for either of us. You have to maintain a balanced life for all the members of your family. Children, even gifted ones, need the security of a strong family. It's also very important as a parent to maintain your perspective and have a solid set of priorities. It's necessary for making decisions that are in the LONG TERM best interest of your child. Perspective and priorities tend to get all messed up when you narrow your focus.
IMO, that's where Pat and I differ. Nothing comes before the health of my kids. No medal on this planet would justify my child's suffering. I would have had my kid off the ice in a heartbeat. I would not have allowed her back on the ice until a Dr said it was ok. Any limits set by the Dr, for example- no loops, would be strictly followed or hell would be raised and put on display.
Maybe my kid would hate me for it. That's ok. I'd rather she hate me for saving her hip, than for not letting her pierce her naval and dye her hair blue.
So, in short, I would willingly make sacrifices. I've gotten good at it. I would not allow our lives to revolve around my child's career.
