question: Hi, I have a 5 month old.  He is totally breastfed.  He always has greenish poos with white lumpy bits and sometimes green lumps.  Also, his poos are very explosive, gassy and smelly.  He hasn't often had a 'normal' poo.  He is also in a lot of discomfort, and he tends to go about 5-7 times a day and very quickly after a feed.  He has also started to be sick after most feeds too, so his gp has prescribed him gaviscon.  This helped for a few days, then blocked him up, so we have stopped it and his paedetrician has prescribed ranitidine, which again doesn't really seem to be helping that much as he wakes up screaming in the night and arching his back.  He is not hungry but just in pain.  Does anyone know what this could be?  Thank you
