A. Hello good evening !! As the baby is 8 months old and takes solids thrice a day - Breakfast , lunch and dinner then milk in between meals 80-100 ml per feed early morning,mid morning and during nap time and night time will be sufficient 500-650 ml . Check if the baby is gaining weight ,then 20-25 ml milk per feed.
