Hi thanks for reply.
His diet is good. He drinks two 8oz bottles per day (morning and bedtime). Bowl of cereal (weet biscuits eetc or porridge), fruit during the day (eased off on bananas), varied dinners (chicken, fish, beef) somedays pasta etc somedays potatoes, one yoghurt each day, toast or crackers in the evening, liga etc then bedtime bottle. he has a good appetite. He doesn't eat much cheese either...
Constipation has been ongoing for at least 4-5 months. He is 100% on cows milk for around 3-4 months so i can't directly assume its the milk but its obviously attributing to it.
I don't like having to rely solely on a lax every day to help him, i would like to try prune juice to see if that helps.
