1 Year Old Got Yellow Stools – Due To Cow’s Milk?

Mom’s Question:

We introduced cow’ milk to our one-year-old daughter two weeks ago. She has approx 150ml cow’s milk plus 400ml toddler milk each day. She eats a balanced diet and I have had no problems in the past.

Since this change she has had loose (not diarrhea) stools which are yellow (similar to when they are very young) which have a strong bad smell. She also seems very irritable. Any advice, please?

Smelly, Runny Stools And Cow’s Milk

Since introducing cow’s milk is the only change you have done to her diet, I would definitely take it out of her diet again and see if there is an improvement.

It is very possible that her loose stools, irritability, and the smell and color of her stools are all related to either lactose intolerance or milk protein allergy.

The color of her stools is not necessarily an issue. Even if it is related to the cow’s milk, the color alone is probably nothing to worry about.

Unless you notice other signs of illness (such as a fever or vomiting), take her off dairy products – either all dairy or start with experimenting with lactose-free products. At the same time, schedule an appointment with her health care provider to discuss if you should test her for lactose intolerance or milk allergy or if you should simply introduce the milk more slowly.

I’ll include a few links about babies with similar issues below.

Good luck!
