My DD (11 months) has recently caught a cold, a sickness bug and a cough after having gone to play groups where there have been other LOs with the same illnesses (obviously I cant prove this scientifically but I am pretty damned sure this is the case). I have always steered clear when DD is not well so as not to pass it on. Is it unreasonable of me to expect others to do the same? And if so, does this give me permission to join in the great germ spreading fest (providing DD is up to it of course)?
