hello,,, No, you are not supposed to worry about green stool,Hello... Green stool is because of Bile is not digested by intestine, Intestine is not matured to digest. Just watch for weight whether it is decreased or increased. If child is gaining weight , then no need to worry. Breast feed is complete food for your baby..up to 6 month to 1 year.(we can not compare breast milk with any other artificial food). Breast milk is produced by interaction between maternal Hormonal reflexes and reflexes in baby, Tow hormones come into ply during lactation- Proplactine and Oxytocin, Factor enhancing prolactin reflex- Emptying the breast, Sucking, Expression of milk , Right feed. Factor enhancing Oxytocin reflex - Confidence in mother, Sound of baby, Sight of baby, Think lovingly of baby. Factor inhibiting both hormones reflex: Feeding with bottles, Inccorect feedin ,Worry, Stress, Pain , Doubt, Embressment etc SO MY POINT IS TRY TO PSYCHOLOGICALLY FIT, AND ENCOURAGE FOR BREAST FEED (THERE ARE LOT OF MEDICINE TO ENHANCE BREAST MILK PRODUCTION FOR THAT YOU ARE SUPPOSED CONCERN YOUR GYNECOLOGISTS ) If still every thing is failure and mother is not lactating, Then Second option is government Buffalo milk, (start with 1 part of milk and 1 part of water , then according to tolerance gradually decreased water quantity ) If second option is not possible then try for milk powder,,,,like soya milk, zerolac, nasobee etc For Green stool - vavdig(vidang)1/4 tsf + Ajavayan 1/4 tsf + !0 ml water made decoration. 5 drops 3 times in day after feed. Thanks: if possible. you can get back to me with the progress in case u need further suggestions. Regards Dr Sagar Mhatre
