I remember making chocolate easter nests year after year as a child and it is a tradition we have carried on with Monkey, and will with LM as she gets older. It is such a great fun, quick, and easy make that kids of any age can join in with.
Monkey did it first 2 years ago at about 10 mths old, then last year at just under 2 and again this year. He still needs quite a bit of help but I imagine he will less and less help as he gets older.
