I started my own kids cooking when they were about 3 or 4 and I've done the same with the grandchildren,my 7 year old GD helps a lot and likes to make omelettes and pasta dishes,simple tomato sauces are a favourite and she can identify a lot of herbs in the garden,the 10 year old makes great fruit salads and makes good pastry ,she likes a quiche so getting decent pasty is crucial...lol. They all love cakes and have great fun decorating them .They get to do stuff their mums wont let them do ,,use knives and a gas cooker so its all exciting By the time my daughter got to high school she was capablle of making a three course meal and we're aiming for that with the girls noow
