OK, I think it worked, if you read this you'll see I think why it would totally out me in RL.
MyDS2 (3 in July) started nursery in November when I started work. He goes 5 afternoons a week.
Before Christmas, he became ill and ended up with viral meningitis in hospital.
In January, he came down with slapped cheek within one week of returning to nursery.
In February, after half term, he was hospitalised with viral pneumonia.
In March. he was hospitalised with uncontrollable temperature and unspecified upper respiratory tract infection.
He has just been treated for and mercifully seems to be recovering very well from meningococcal disease, and is now receiving IV antibiotics as an outpatient having been critically ill in hospital.
Every holiday, he has been fine. Record length of time at nursery before something (the above are the serious and in some cases terrifying ones) happens is one week.
Is this a coincidence, or should I (as several of my friends have suggested) be considering whether nursery is the problem and I should maybe be looking for a smaller setting, like a child minder maybe?
