Hi, If the baby sleeps a lot and gets up for feeding every 3 to 4 hrly that is good. If the weight gain is good no need to worry .if the feeding is poor or baby wakes up frequently and remains irritated ,u need to start worry about her intake of milk ,it may be insufficient. Also now you can start on complementary feeds like smashed potatoes in dal soups or finely cooked ( liquid consistency ) rice porridge and rice dal khichadi ,or rice with vegetables soup .
