Their favourite dinner at the moment is pumpkin soup - the cook at Mr Three's pre-school makes a very popular recipe so it's at the top of their request list. OK, pizza is also on their list, but pizza doesn't have to be unhealthy - the Sophia pre-school cookbook has a pizza topping that includes mashed kidney beans for low fat, good quality protein.
One tip I picked up last week is to offer the raw food first - give your children a carrot stick before dinner. And it doesn't just apply to children - most adults, including me, would benefit from one.
The other classic kids food I haven't introduced yet is alphabet pasta - I reckon my boys would love that. Slip it into soup and they will slurp it down (although I anticipate a bit of mess with the attempts at spelling).
My friend has a good suggestion - put a hard-boiled egg in your children's lunchbox and write a funny message or draw a face on the shell. Peeling an egg by yourself is one of life's joys when young.
The owner at Sophia pre-school, Adrienne, had a great suggestion - make a rule of "don't be rude to food". Unfortunately, even with the few good tricks I practice, I am increasingly getting criticism of my labour of love in the kitchen - it is pretty frustrating when the calls of "that's disgusting" happen before a bite has been taken.
I've had a chat with my boys about this approach and I'm hoping the phrase will stick in their minds. Wish me luck.
Another good idea I will eventually try out myself is making ice-cream out of frozen bananas - a simple concept of processing frozen bananas in a food processor with some nuts or chocolate chips. It illustrates that making healthy choices doesn't always have to be expensive (when bananas are in season) or complicated and time-consuming.
Adrienne said she found it sad that many children did not understand where food came from - "The supermarket" was the typical answer.
I tested Mr Three this week with, "Where do apples come from?" and thankfully he answered "the garden" so we have a pass mark there.
I will continue this journey of teaching my children healthy eating habits when they're young - and hopefully I will learn a few things, too!
