Babies can safely eat yogurt when they are ready for solid foods, around 6 months old. Yogurt provides nutrients like protein and calcium, and can be beneficial for babies struggling with weight gain. It is best to choose full-fat yogurt for babies under 2 years old for brain development. Yogurt may also contain probiotics that support a healthy gut. However, if a baby has a milk protein allergy, they should avoid yogurt or consult with a pediatrician. Introduce yogurt gradually and monitor for allergic reactions. Never serve yogurt with honey to children under 1 year old. Breastmilk or formula should still be the primary source of nutrition for babies.
