Thanks for the query
Change in bowel pattern with change in consistency and color of stool is common during transition feeding.Now this is the age when you should start complementary feed for your child. Start with rice then wheat then pulses then egg. If there is any allergy
or feed intolerance you can easily identify the substance causing it. You can give rice curd, dalia, dal, egg white, suji ka halwa, khichadi etc. All these will help in establishment of normal bowel habit. If you are giving formula milk then check the dilution. A change in ratio will lead to improper growth and also more disturbed bowel pattern. As you have mentioned your baby is doing well developmentally.
I hope this answers your query well
