Please don't self medicate your infant po. Consult your pedia po muna kasi it could be a number of reasons why they can't poop. And kung bibigyan lang sya ng gamot everytime hindi sya makapoop without addressing the root cause, hindi po sya long term solution.
Reseta ba yan sa kanya? If not, bakit ibibigay? Kung nahihirapan magpoop yubg bata better na magpaconsult sa pedia.
