6month old baby suffering Colic pain.

Hi Doc, My 6month old baby is on lactogen stage 2 formula milk...before he was on lactogen 1 from birth...he is recently turned 6month so we are giving him Lactogen stage 2 formula milk...he drinks breastmilk also...his stomach gets upset after drinking lactogen 2, also his poop color changed in loose foaming light yellow...before on lactogen 1 he do gray greenish mix poop... And he is on supplements also....his birth weight is 2.6kg...and now 6 month old- he is 8.8kgs 1)Calshine P drops -0.5ml a day 2)BEVON Drops -0.5 ml a day 3)Calcimax-P syrup -3ml twice a day 4)Tasiron drops -5 drops with like warm water twice a day In solid he eats boiled apple puree in the afternoon. Why he is having colic pain often? He cry so much when we give colimex drops then only he feels good ... Is these drops are too much for a 6month old baby?
