Unfortunately this runs in the family. My four year old daughter is still on Movicol after a year and my husband only goes once every four days (he'll love me for sharing that!) My seven week old son is filling his nappy with the usual mustard, but only every other evening and seems to have belly-ache in between. (I'm half breast/half bottle feeding and using Cow and Gate Comfort to help with colic.) My mother suggests a bit of demerara sugar in his bottle, but I'm not keen on that idea. Any suggestions?
