(Inspired by the thread about a 5 year old's project.)
Did you do or help much? And if so, was it because you knew other parents most certainly would, and you didn't want yours to lose out by comparison?
When I was working at the local library, we knew very quickly when one of the nearby primaries had set a half term or holiday project, because the first sharp-elbowed parents would be in at once, trying to clear the shelves of every last book on the Tudors, or the Vikings, or whatever it was.
We ended up having to restrict how many they could take.
Then there were invariably the poor parents who'd only just found out about it, and would come in 2 days before the end of the holidays, desperate for anything.
I certainly remember among other things, painstakingly colouring in a woodpecker at midnight, so that a dd's 'Birds' project would be finished on time - she had gone to bed very late, tearful and exhausted with it. I used to hate the nagging that had to go on during the holidays, to get them to get down to it.
When other dd was about 12 she was supposed to be making a cookery apron at school - the exact same thing I'd hate to make nearly 40 years earlier! Since dd loathed needlework and still does, I did eventually finish the wretched thing for her (did most of it TBH) and since I'm pretty competent at sewing I was very put out to get 'C+. Neatness and accuracy are 2 skills which you must practice.'
But it least it gave me a laugh, since it should have been 'practise'. I was forbearing enough not to point it out to her at the next parents' evening though.
(Sorely tempted though I was. ?)
