I think it's okay to feel jealous, but it's how you deal with it that's the important thing. You have to be happy for your friends when they do well because you want them to do well. It's not a competition.

All my grandchildren bake. On a Saturday, Annabel's boys, Louis and Toby, always bake. Louis makes a chocolate cake, Toby makes banana or lemon drizzle. They're 12 and 10, and they can do it totally on their own. My son's twin girls, Abby and Grace, are 14; they make birthday cakes and like to do it on their own with Mum out of the way.
