DD2 has always been quite thirsty but seems to be drinking more than ever lately. She can get through a huge beaker of water, with or without juice added, in a couple of minutes and be asking for more straight after. She's also weeing a ridiculous amount and one nappy no longer lasts anything like a whole night. Is this just a normal and healthy response to the warm weather or should I be worried? I did wonder about diabetes but surely there'd be other more major symptoms like weight loss if it was that?
