Honestly mama, I'm not super familiar with those specific brands or products, are they vitamins, formulas, or something else? Best to check with your pedia kung okay talaga silang i-combine, kasi baka may overlapping nutrients or ingredients na hindi maganda for your baby, especially at 6 months pa lang when they're still so sensitive! Better safe than sorry, diba, kaya I'd really recommend asking your doctor first bago mag-experiment.
