my son is going to be 8 months old but he shows no Interest in eating fruits and cereals... is it a serious matter of concern and what to do

A. You can give fruit milkshakes and fruit smoothies using breast milk or formula milk. Try finger foods. Many babies are keen on that. Babies at this age have identity of self, express their needs and refusals. Consider adding some variety to the cereal. Persistence is the key. You might have to offer the same food 10-15 times before the baby starts having it.
