Families who bake regularly
If pancakes, muffins or sauces often call for milk, unopened UHT cartons can be kept until a recipe needs one. Check how quickly your household will use each carton once it is opened.
Who is this for?
Families with children under 5
The child’s age changes the drink decision. The NHS says skimmed milk can be used in cooking from age 1, but does not recommend it as a main drink for children under 5. Product-specific warnings still need checking.
Parents packing lunchboxes
A six-pack of 1-litre cartons supplies milk for use at home, not separately packed drinks. If you need a lunchbox portion, check both its size and whether it is skimmed: individual 200ml cartons listed by Next Day Coffee are semi-skimmed.
What should you check?
Decide how much milk your recipes use, then consider storage after opening and whether any of it is intended as a child’s drink.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Check the number of cartons and volume per carton; plan recipes around the amount you can use after opening. | I bake often enough to use a 1-litre carton once it is open, but want the remaining cartons unopened for later recipes. |
| Storage | Read the unopened and opened-carton instructions separately. Waitrose & Partners says its Essential Long Life Skimmed Milk must be kept below 5°C after opening and consumed within 5 days; follow the instructions on the pack you buy. | Cupboard space helps me store unopened milk, while fridge space and the time available to finish an opened carton determine which size to choose. |
| Children’s use | Separate recipe use from use as a main drink. The NHS permits skimmed milk in cooking from age 1 but does not recommend it as a main drink under 5; also read any warning on the specific product. | If I am baking for a child under 5, I need to check the carton’s warning. I will make a separate decision about their everyday drink. |
| Lunchbox portions | Check the milk type, millilitres per portion and whether each portion is a drink-sized carton rather than a catering pot. | For a separately packed drink, I need an individual portion; a 1-litre recipe carton does not meet that need. |
| Milk allergy | Check ingredients when preparing food for a child with a cow’s-milk allergy. NHS child-health guidance distinguishes an allergy to milk proteins from lactose intolerance. | When a child has a suspected or diagnosed cow’s-milk allergy, I cannot assume ordinary or lactose-free cow’s milk is a suitable ingredient. |
Mistakes to avoid
-
Treating baking milk as a young child’s main drink
The NHS allows skimmed milk in cooking from age 1, but does not recommend it as a main drink for children under 5 because it does not contain enough fat.
Keep the recipe and drink decisions separate, and check warnings on the milk you buy. The Morrisons six-pack shown below carries an under-5 warning that needs clarification before use in a young child’s food.
-
Choosing small catering pots for lunchboxes
A catering portion is not necessarily a drink-sized carton. Next Day Coffee lists semi-skimmed catering pots and 200ml cartons, so their size and milk type differ from a skimmed 1-litre baking pack.
Check the volume and milk type on each individual portion before buying it for a lunchbox.
-
Leaving UHT milk out after opening
The cupboard-storage advantage applies to unopened cartons. Waitrose & Partners instructs buyers of its Essential Long Life Skimmed Milk to refrigerate it below 5°C after opening and consume it within 5 days.
Open one carton at a time and follow that carton’s own refrigeration and use instructions.
-
Assuming lactose-free dairy milk avoids a milk-protein allergy
Cow’s-milk allergy concerns milk proteins, which is different from lactose intolerance, according to NHS child-health guidance.
Do not substitute another dairy milk for a child with a suspected or diagnosed cow’s-milk allergy without appropriate clinical advice.

Morrisons British UHT Skimmed Milk, 6 × 1 litre
Six 1-litre cartons suit recipes that use milk at home, with unopened UHT cartons available for later baking. The product description says to refrigerate after opening and use within 3 days. It also says the milk is not suitable for children under 5 without clarifying whether that warning covers use in recipes; ask the seller before using this particular product in food for a child under 5.
Common questions
Can I use skimmed milk when baking for a child under 5?
The NHS says skimmed milk can be used in cooking from age 1. Check the specific product too: the Morrisons six-pack shown here carries an under-5 warning that does not clarify recipe use, so ask the seller before using it in food for a child under 5.
Is skimmed milk suitable as an everyday lunchbox drink for a child under 5?
The NHS does not recommend skimmed milk as a main drink for children under 5 because it does not contain enough fat. That guidance is distinct from its use in cooking from age 1.
Will a six-pack of 1-litre cartons work as individual lunchbox drinks?
No: the skimmed UHT multipacks listed by Tesco Groceries and Sainsbury’s Groceries contain litre cartons for household use, not separately portioned drinks. Check both portion size and milk type if you need individual cartons; the 200ml cartons listed by Next Day Coffee are semi-skimmed.
How should I store skimmed UHT milk after opening it?
Follow the instructions on the particular carton. Waitrose & Partners says its Essential Long Life Skimmed Milk should be refrigerated below 5°C and consumed within 5 days after opening; the Morrisons six-pack shown here specifies refrigeration and use within 3 days.
Can lactose-free cow’s milk replace ordinary milk for a child with cow’s-milk allergy?
Do not assume it can. NHS child-health guidance explains that cow’s-milk allergy concerns milk proteins, whereas lactose intolerance is different. Seek clinical advice before choosing a substitute for a child with a suspected or diagnosed allergy.
