Whether you're a new mum starting to breastfeed, a seasoned pro or considering the option to express, you'll know it takes time, energy and a lot of patience. That precious milk is liquid gold for your little one, so keeping it safe and fresh is a top priority. That's where a mini fridge for breast milk can offer a helping hand. These handy gadgets have recently become popular with parents looking for practical solutions, especially in those first few chaotic and messy weeks after having a newborn.

If you're expressing, you probably store your milk in a sterilised container or a breast milk storage bag before popping it in the fridge. While the NHS recommend storing your breast milk in the fridge at 4C or lower for 8 days, a smaller mini fridge in your bedroom can save you from those groggy late-night trips to the kitchen. They offer a compact and convenient place to pop your milk before bedtime to ensure it stays cool and ready for when hunger calls. Plus, if you're exclusively pumping, a mini fridge is the perfect safe place to pop any milk that's been expressed overnight. Just remember to move it to your main kitchen fridge in the morning, because - here's the important bit - mini fridges don't maintain the same low temperature.

Unlike a kitchen fridge, which has a fixed temperature of between 0°C and 5°C, which helps to slow down bacterial growth and keep food fresh, a mini portable fridge is less powerful and works according to the ambient temperature of the room. Therefore, the cooler the room, the cooler the fridge temperature and vice versa - something to bear in mind during the warmer summer months. If in any doubt, use a thermometer to check the temperature of your fridge to ensure it is safe for breast milk storage.

It's also worth paying attention to the energy efficiency which can impact the cost of running it and the environmental impact. As with all energy ratings, they go from A to G, with A being the most efficient and least costly. You can see the cooling capacity and energy level of each mini fridge below.

The best mini fridges for breast milk

Russell Hobbs 4L/6 Mini Portable Cooler

Best overall mini fridge for breast milk

With a grey gloss body and wood effect accents, this mini cooler combines functionality with Scandi style. Lightweight at 2kg and whisper-quiet noise 27dB noise level, you won't even notice this mini fridge doing its job. One mum said, "I've been using the Russell Hobbs Mini Fridge in my bedroom to keep breastmilk cool and ready for night feeds, and it's been a game-changer. The fridge is the perfect size – compact enough to fit neatly on a bedside table, but still holds several bottles. It comes with lots of adaptors, including for both mains and car use, making it really versatile. The fridge does exactly what I need it to, keeping milk at the right temperature without taking up too much space. The only downside is the green light on the back, which is surprisingly bright at night. I've had to cover it to stop it from disturbing my sleep – a small fix for an otherwise great little fridge."

  • Scandi style finishes
  • Comes with carry handle

Abode Blue Mini Fridge

Best mini fridge for breast milk with a retro design

We love the retro design of this compact fridge, which can easily be moved from room to room thanks to its carry handle. The pop of colour also adds a little character and can easily fit in with complementary nursery decor. It can cool to 16°C below ambient temperature, so it can be used to store expressed breast milk if your room isn't too hot. When you no longer need it to store your milk, it can be used to store food, snacks and drinks for days out, camping trips, or long car journeys. One review said, "Bought this to keep in the bedroom for my wife to put cool packs in, ready for her next migraine. We were concerned it would not be quite enough or cold enough. Both concerns were quickly dispelled. It’s whisper quiet and very cold in fact there was ice in the back one morning and on occasions the cool pack we keep in it is too cold to put on her forehead...We have it on a timer to come on at 9 pm and go off at 8 am and it’s perfect."

  • Available in four colours
  • Handle on the front
  • Retro design
  • Comes with carry handle
