My child’s breath has a rotten egg smell

At 11 months, the main diet should comprise breast milk

Dear Dr Ombeva,

My baby girl is now 11 months 2 weeks old. She is a good feeder, but two months ago, I observed that sometimes she would get the foul egg smell. I have given her extra quantities of roughage and water to reduce all this. I would like to know if there are specific variety of foods I should give her especially for breakfast, snack, lunch and dinner as well as the required portions.
