[Margaret Pilkington]

While I would never admit to being one of those G things....I think that you do your utmost to help your children.
If that means you care for their children, then you do it in a way that suits you.
After all it worked when you were bringing up the parent of this child...so what has changed(apart from us getting older and a bit more wiley)?

As for experts....I always tell people that this is the definition of an expert.
X marks the spot....and a spurt is a drip under pressure.

Common sense, kindness, a sprinkling of fun and silliness and the continuity of someone who loves them is all any child needs.
