Food flask

Terrific product. My primary school age son was sending uneaten sandwiches back every day. He asked for one of these (having seen it in his class) and now demolishes a healthy, warm lunch of largely of leftovers every day. He’s doing much better and I don’t have the dread of making a sandwich every night after work which I know will be sent back untouched the next day.

Thermos food flask

Love this product. Ideal size for what I need now for my baby's weaning needs. Keeps food nice and toasty when I'm out and about.

Ten out of ten!

I was recommended mummy cooks by a friend for our daughter who had her first baby in lockdown in March. I cannot say enough. Your weaning set, receipe book and food flask have been the best things she has had. She said it gave her the confidence to move forward and try all your advice ! She’s loves it. Thank you thank you!

Love the products

I bought a set of weaning pots for my baby starting on solids and they're the perfect size for her stage. Purchased a food flask also and it's perfect for taking hot/cold lunches on the go. Perfect for picnics and trips out!

Perfect flask for school

I bought this for my 10 year old son who doesn't like sandwiches but loves pasta, stir fries etc. So now I can give him lunches that he will eat and enjoy. The flask is a perfect size and doesn't leak and is easy to wash. I filled it at 8am and lunch was at 1pm and was still hot. Just right for my son. Excellent product. I buy the portion sets also as they are great for smaller snacks in the lunch box.

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!
