This is the third time in as many weeks we've been to the doctor with ds (11 months) - first he had an ear infection, then an rash plus upset stomach and now a chest infection. All proper, making-him-poorly illnesses but I'm beginning to think they must think I've got Munchausen's by Proxy or something. He's not even a pfb - I think dd has only been about 3 times in her life, she's just a hardier soul.
So, do you have a rule of thumb - e.g. temp of over 38? off their food? looking sad?
