Love the flask

I have tried many flasks but this one is just too good, nice and colourful Comes with stickers and instructions; really happy with the flask, my kids can now how home cooked meal for school lunch, and food stays really warm after few hours of prep, highly recommend it if your kids don’t like sandwiches or cold wood for school lunches. My fussy children’s problem is solved, thank you.

Thermos food flask

Game changer for school lunches, giving me more options to offer my fussy eater especially with the colder weather setting in. She’s loves having warm food at lunch time

A little about us

Hi, I'm Siobhan!

I'm a Mum of two girls with a passion for nutritious, home cooked food. When I started to feed my first daughter Ashleigh, I loved to batch cook her baby food. It frustrated me that it wan't easy to get hold of decent quantity, practical little pots without them costing the earth. I therefore decided to create the best solution for portioning and freezing food.

I set up Mummy Cooks as a way of inspiring, educating and empowering parents to feed their children healthy, home cooked food.

Our Weaning Pots

Our Weaning Sets include all the portion sizes you need to support each stage of your baby's feeding journey. You will have plenty to batch cook and freeze portions for later use; so you can spend less time in the kitchen and more time having fun with your baby. They're also perfect for carrying snacks when out and about.

We hope you enjoy our pots and that our products help you give your child a love of nutritious home cooked food... just like I've given my two girls.

Happy Feeding!
