Nicky - a quick answer to your quick question - Liam isn't bad in the heat, although today & the other really hot day we had he was in daycare, in airconditioned comfort. He does seem to get a bit tetchier, and his eczema flares up a bit, although it's hard to know if this is not also brought on by a bit of teething that's also going on. And he drinks water like it's going out of fashion, starting to make me wonder about diabetes, although I'm pretty happy that he's so keen to drink the stuff, it's a healthy way to be.
