So ds is all scabbed over, went back to school today and no I didn't take him out.
However..
Dd hasn't had it and has no symptoms. She was obviously in very close contact with ds all the while, so seems highly likely that she is currently incubating (although I am still bfing her, no idea whether the antibody thing still happens at nearly 2yo). I had thought I would keep away from toddler groups for a couple of weeks, where she is likely to be sharing toys and be in very close contact with other children and possibly pregnant women or newborns, but not keep her in otherwise.
All the mums I've spoken to today though seem to think I'm overreacting and should just carry on as normal. WWYD? There seems to be a CP outbreak going on around here, local pre-schools and schools have cases, so there are probably lots of contagious pre-spot children around.
