My 8 month baby contstantly loose weight. Please suggest how to increase my baby weight

A. Ongoing weight loss in young infants is commonly caused by acute infection, problems with feeding, milk protein allergy, malnutrition, or failure to thrive. Gastroesophageal reflux disease, pyloric stenosis, and child neglect are other frequent etiologies. Dehydration associated with any etiology can be severe.Some babies may lose a little weight around this time. This could be because they're moving more, they have been sick, or they're not eating enough of the solid foods you're giving them. They might just be more interested in playing than eating!
