A. during the summer season it is important to keep baby well hydrated.. give coconut water butter milk lemonade rice water, cucumber, watermelon.. plenty of fluid and water.. try to develop food interest.. have meals together.. add variety and creativity.. let the baby have his own food.. give natural appetizer as coconut water ajwain water or jeera water..
