I live in a house that is on a development which have quite extensive communal gardens that lead down to the Thames. When I have my 4 year old granddaughter for the day she wants to go down to the water's edge where there are moorings as she likes to look at the boats, I'm always nervous and insist she holds my hand when she gets too close to the water, which she sometimes argues about, but I always insist she does. The river is swollen at the moment and when she saw a fast moving large piece of branch moving quickly in the water, she thought it was a crocodile, to which I replied "it is and there are quite a few more, so lets not get too close!". It's a bit of white lie but I'm working it to my advantage at the moment.
I sympathise with a lot of the posts, although I enjoy having her, nevertheless I'm glad to hand her back at 7. I don't remember my children contradicting me so much at this age, but they were boys and spent most of their time exploding!
