DS (2 tomorrow) been grouchy since the weekend, waking early crying which is unlike him. Appetite not what it usually is. Yesterday morning he started with a rash - like very small red pimples on his body, arms, legs. The rash hasn't changed, neither worse nor better since then. Looks like a heat rash to me.
I've never seen the early stages of chicken pox, could this be it? I just remember the big blistery spots. It is going round his nursery at the moment.
