It's not easy to see from the start but you will be able to pitch your tent, I promise.
Search youtube (and the manufacturers web site) for video pitching tutorials ... almost every tent is there somewhere.
Find the children something to do ... fetching water is a good job to get them out of the way.
Never be afraid to ask a neighbour to come and hold a pole or two ... most folk are happy to help if they're not busy themselves ... besides, it's a splendid ice-breaker.
You will find you have left the stress at the gate
