Patient: I have a 18 month old girl who weighs 9.9kg. She was on formula till 12 months and now on cow milk. Normal diet. She struggles to poo and has caused herself to tear many times. It isn’t very hard to say it’s constipation. She has never ever had a brown poo it has always been a mustard colour mixed with a sand colour. Although over the past week it has just been the sand colour. She finds it very difficult to poo and holds it it. I have tried parrachoc and different laxitives to help but this is not a solution the colour is a worry. She also has really bad eczema.
