Breakfast is such a brilliant meal - you really can have anything. I remember when I was small that the best bit about a sleepover was having a different breakfast from usual (one of my friends had cheese sandwiches, which I thought was fantastic).
Anyway, my nearly-five-year-olds have breakfast at nursery four days a week - it's either rice krispies, cornflakes, shreddies, or toast with butter. Well, it is for ds2; ds1 has coeliac disease, so can only have rice krispies out of that list.
At home, they like three courses. Porridge (I make it with millet flakes, as oats are a no-no) with a dollop of honey or jam; nazi no-added-anything cereal (puffed teff, at the moment, because I got sent some as a sample - it actually tastes like wheat, which is nice) with raisins; then toast/gf bread. I try and keep portions sensible - all three together probably add up to one of the bowls of cereal they get at nursery.
At their aunty's house, they like gf cinammon bagels with nutella. If their dad is doing breakfast, they like scrambled eggs and beans on toast. Breakfast on a plate is very exciting.
And only just on topic, I would also like to share how much it pleases me that if you are texting someone to say that, alas, you can't meet for breakfast after all, and type in 'kisses for everyone', predictive text gives you 'kippers for everyone' first.
