Lactaid for 18 month old?

My 18 month old daughter is lactose intolerant. However, I've noticed that all of the milk for lactose-intolerant people is low-fat, and she should still be getting whole milk.

So I have 2 questions: Is it okay to give her Lactaid? And how much fat does she really need at this stage?

Thanks so much,

Dear Michele,

The reason for not suggesting that children under two drink low fat milk is because they need the concentrated calories. Their tiny tummies preclude them from eating volumes of food, so what they do eat must be power packed. If low fat milk is used, the child may not be able to eat the calories they need thrive. Until your daughter reaches the age of two, I recommend that rather than giving her lactaid, which may be hard, purchase the lactase enzyme that you can drop in regular milk to convert it. Usually this takes overnight, so you will want to add the enzyme to whole milk in the evening to have it ready for your daughter the next day.

Until the age of two, it is wise to have fat be no less than 30% of her calories. If she is consuming around 1300 calories a day, then she should be eating about 44 grams of fat.

Thank you for writing.
