BABYGO® Reusable Silicone Breast Milk Bags (5 Pack)

£25

Reusable milk bags that stand up to fill and lie flat to freeze

If you're pumping most days, single-use bags go in the bin almost as fast as the milk goes in the freezer. These five silicone bags wash and go again, so you're not forever buying more.

Each one stands up on its own while you pour, with a wide opening so milk goes in straight from the pump, and markings on the side up to 240ml (8oz). There's a panel for the date and amount, and a pen comes in the box.

The top closes with a double seal, and there's a separate capped spout for pouring into a bottle. Freeze them lying flat and they stack neatly.

When you've finished expressing, they're just as handy for purées and batches of soup.

Questions, answered.

How long can breast milk be stored in them?

The NHS says expressed milk keeps for up to 8 days at the back of the fridge at 4°C or lower (within 3 days if you're not sure of the temperature), 2 weeks in the ice compartment of a fridge, and up to 6 months in a freezer at -18°C or lower. Write the date on the bag before it goes in the freezer.

How do I defrost milk in them?

Slowly in the fridge is best, or stand the bag in a jug of warm water or hold it under warm running water. Don't use a microwave or the hob, as they heat unevenly and can leave hot spots that burn your baby's mouth.

How do I clean them?

Put them in the dishwasher, or wash them in hot soapy water, getting right inside through the wide opening. Stand them open to dry completely before you use them again, and sterilise them as you would the rest of your feeding kit.

Will they leak?

The double seal at the top and the cap on the spout are there to stop that, and people who've switched from disposables tell us theirs haven't. When you freeze milk, leave a little room at the top, as it expands and a full bag puts pressure on the seal.

How many will I need?

Five covers occasional pumping and a small stash in the freezer. If you're pumping every day, you'll want more in rotation, so some can be frozen while others are washed and drying.

Customers say these silicone storage bags seal securely, are easy to fill and clean, and feature clear measurement markings. Many reviews mention their durability and quality construction, with users reporting months of reliable use. The wide opening makes pouring simple without spills, and the bags stand upright in fridges for convenient storage. Common feedback includes appreciation for their role as a sustainable alternative to disposable bags, with several customers noting significant cost savings. While most find them easy to clean, some mention they can be slightly challenging to dry completely inside. The five-pack size receives positive comments for providing good rotation options.

    A little delayed but well made: stacks neatly when frozen

    First impressions were good and it has held up well. They stand up while filling and stack neatly once frozen. Cleaning takes a little longer than I expected, but the performance is good.

    Clear markings and strong seals (useful with one small caveat)

    The seals close firmly and the bags lie flat without leaking. Delivery took an extra day, but it was worth waiting for. I freeze them flat and file them upright afterwards.

    Good quality, eco-friendly choice

    Really pleased with these bags. They seal well, are easy to fill and clean, and the measurement markings are clear. Slightly fiddly to dry fully inside but a bottle brush sorts that easily.
