Prama - I noticed the crystals in Jaz's nappies when I used Huggies. I changed to V.I.P.s & haven't had them since. They are made by the same people. Can't get them here though.
I think it might be something they put in disposibles so they stay dry?? Not too sure though.

Jesse doesn't have teeth yet, but they are moving around in there. He gums everything. He was a bit irritable a few days ago too, with one red cheek. But he's ok for now.
