My baby has bad reflux and was prescribed gaviscon infant which has worked however has given his really bad constipation. It has been about 5 or 6 days since he has had a proper poo. He is EBF he keeps pushing resally hard that his face goes bright red and only a pea sized hard poo comes out. I have tried warm water massage excerise etc nothing is workinf. What can I do? I read on an american site diluted prune juice but he is not weaning as yet so not sure this is an option. He seems in pain please help. Thanks
