how old is your little one? Our baby is just over 10 weeks old, 2 weeks corrected and we have been giving him an oz of cooled boiled water in between every couple of feeds to help with his constipation, not sure if any other mummies have been advised differently but we checked with the midwife,HV, doctor and baby clinic before we gave him it and they said it was ok, plus it helps clean their mouths out.
