Wow, I'd be so ****ed about that. Not just because it made my children feel crappy about their hard (and genuine) work, but also because what's it teaching that child exactly? To rely on mummy or daddy to do things for you? That's cheating IMO, it's pretty much teaching your kids to not follow instructions properly and to cheat. False self esteem, right there, and any guesses which kids are going to grow up ****y and full of themselves...the ones whose parents do their projects for them, and then get undue praise for the work. I remember distinctly that happening to me at school a lot, not cool.
