to not want ds to go to a party and jump on a trampoline without a net?

[rosybud]

Ds (8) has been invited to his friend's party to swim in an (unfenced) pool and jump on a trampoline without a net.

I am not happy about this.

We don't have a trampoline so ds is not an experienced jumper, the other boys are bigger/heavier than him. Dh is very concerned as I am...but I know ds will feel i am being overly cautious and spoiling the fun!

Do I stand my ground and insist he is not to go on the trampoline or am i over-reacting?

Before we all jump to conclusions about hordes of unruly kids leaping all over it, why not give the host mother a modicum of sense and have a word with her. Tell her your concerns, see what she has to say about it, she'll likely reassure you about the safety, hopefully she'll tell you that she will be supervising them. Then you can make your decision based on that.
feel it would be really hard on your ds if he were stopped from going because of what may happen.

As someone who is all for adventurousness in childhood and risk taking - I am happy for my dd to climb trees etc - I am convinced there will be injuries if more than one child is on the trampoline at the same time.

My child has had quite a lot of tramplolining lessons and we have a trampoline in the garden (with a net). This leads me to believe that having had lessons and having "good technique" does not make you less likely to be injured by someone else crashing into you, particularly if that person is heavier than you.

There are a lot of other ways to have fun, and if my dd broke an arm in a party situation like this I would feel that it was my fault.
