@docadams, thanks for the response, I use a reputable private hospital on the mainland and the last doc I saw is a pediatrician, she was the one that advised on the fruit diet after evaluation.
@McSquishi, no I don't have prune juice available, will ask around though. Thanks.

Please mothers in the house, I need your help. My 7-month old baby has not been pooping, and even when he manages to poo after much straining and crying, it comes out very hard, sometimes with blood. This has been going on for more than a month. I've been to the hospital twice, and undiluted orange juice and plenty of other fruits with enough water was the basic recommendation, but up till now the problem persists even with the everyday fruit diet. For home remedies, I've been advised to put baby mentholatum in his anus, some recommended olive oil or liquid paraffin for easy passage of d poo, but nothing seems to be working. I've also tried massaging his tummy and making him seat in warm water, all to no avail. I even stopped his cereal temporarily and was giving him pap instead with his follow-on formula (he has stopped active breast feeding), but it's not getting better. Mothers please advice, what else can I do?
