Baby is 7 months old and her weight is 4 kg . What should we do

A. The babys weight is way under the average weight.Did you check the cause with her doctor? was the kid fed every 2 hours the first 6 months?as she is now 7 months you can start with solids 3 times a day.In between five her snacks twice a day along with milk 3 times a day. Try for a week and see if she has atleast gained 100 grams if in spite of proper food she is not gaining and is physically active dont worry.In case she is dull then please check with a doctor.
