I am totally guilty of underestimating my children! My mum bought them some models to decorate with Decopatch papers and I really didn't think they would manage very long sat doing it, so I decided just to do one dinosaur with them as it tied in with our theme. I planned for them to do one side each, a bit at a time over a few days.
I was very wrong! Charlie repeatedly singed 'more' to keep going and finished his side all in one go and James was just fantastic doing his side, he even said 'brush' in the end for brushing on the glue, and he sat for about half an hour until he'd finished the lot!
