What kinds of plan/nut milks do you use as a substitute to cows milk?
You can use cows milk in food if there isn't an intolerance or allergy.
Like Ali said you can use any nut or soy milk but not rice milk. If LO is allergic to cows's milk though you you might not be able to use the soy milk (if MSPI).
There are MSI formulas available although I hear they taste awful so perhaps not something you'd want to use in cooking if it's for the whole family.
LOs under 1yo shouldn't be given any milk other than breast or formula as a drink, but it's okay used to make solids with.
Here's a bit from the UK NHS website on milk:
Soya drinks and other milk alternatives
You can give your child unsweetened calcium-fortified milk alternatives, such as soya, almond and oat drinks, from the age of one as part of a healthy balanced diet. Toddlers and young children under the age of five shouldn't be given rice drinks, because of the levels of arsenic in these products (see more below).
If your child has an allergy or intolerance to milk, talk to your health visitor or GP. They can advise you on suitable milk alternatives.
Rice drinks
Children under five shouldn't have rice drinks as they may contain unsafe levels of arsenic. Arsenic is found naturally in the environment and can find its way into our food and water. Rice tends to take up more arsenic than other grains.
Don't worry if your child has already had rice drinks. There's no immediate risk to them, and there are unlikely to be any long-term harmful effects. But to avoid the possibility of them taking in any more arsenic, it's best to switch to a different kind of milk.
The special milk formula (for MSPI) can be bought over the counter from certain pharmacies in the UK but not all pharmacies would necessarily stock it. And it is expensive. And, yes, it is usually on prescription but doesn't have to be.
