DD is 10mths, has had a bit of a cold for a while and is quite congested generally. Now she's also got a bit of a gacky eye, at first I thought it was just sleepy dust (do babies even get sleepy dust? And what's the proper name for it, while I'm at it?) but it's been a couple of days now and is quite a bit worse, greenish yellowy gunk in the corner of her eye and sometimes the inside of her lower eyelid. We've been using boiled cooled water and cotton wool to bathe it which clears it temporarily and I was going to take her to the HV clinic this week just to get it checked but is there anything else I should do in the meantime? And am I in fact not worrying enough?
