Ive been doing this unwittingly for over 10 years before it became a 'thing.'
Best tips are meal plan, if you are busy and to keep it simple.
Mid week meals that are quick to make at home and are child friendly are things like pasta bake, home made fish cakes, home made burgers, shepherds pie, chili con carne spaghetti bolognaise and home made pizza. I use a 2 ingredient dough to make the base.
My kids are grown up but I wouldn't buy cereal, I remember calling it shit in a box and all these years later I was proved right although for different reasons!
Breakfast for the kids was scrambled egg or poached on toast or porridge.These days I have full fat Greek yogurt with seeds and nuts
A lot food aimed at children's very high in upfs. As a rule of thumb if its in a bright package with cartoons on avoid!!! It is much cheaper and healthier to buy a kilo of Greek yogurt and add flavourings individually than little pots of yogurt that are loaded with sugars and stabilisers.
Don't knock making your own bread!! It takes a couple od minutes , if that to put in a machine and it does it for you. I have picked up a bread making machine for 15 quid from Face book market place.
Of course you dont have to do this but look for the best bread you can.
You dont have to get it right 100% of the time. Its just about being more aware of what you are buying and eating.
There are loads of ideas on Instagram, tik tok and face book.
