In the last week, my little one's nappies have been very gritty/sandy? I know that they're supposed to be mustard-like, but this is different. Same colour as the rest of the nappy, but has tiny grains, almost like sand, in there. He's only breastfed, so no diet changes. But, seems to be really pushing and straining when he goes.
Google has worried the heck out of me, so I just wanted to see if anyone could put my mind at ease?
