Mum to 3 month old. We have been v clear with friends and family that if we have visitors, it is on the basis that no one is sick. We were invited round to friend‘s house on Xmas day, when we got there, friend’s DM was clearly ill with a cold - tissues in hand, sniffly, sneezing etc. Someone asked if she was sick and initially she said something about onions making her sneeze, and then the second time, said yes, it’s suddenly come on and she must have caught from her granddaughter (friend’s DD) who had the sniffles. If we had been given a heads up, I wouldn’t have taken my own DS there. DS ended up with a cold a few days later, thankfully not horrendous but snotty and congested for 2 weeks. Relatively certain he caught it there as we hadn’t been anywhere/out of the house around Xmas. Yesterday friends asked if they could visit to see baby. They arrive and mentions their DD has had a temperature and that she’s probably teething. This morning, get a message saying she’s come out in spots overnight and suspected chickenpox, later confirmed by GP. AIBU to be annoyed that my DS has been exposed to chickenpox? Given they know our stance of sickness, should they have given us a heads up that DS may be under the weather, and given us the choice as to whether it was ok that they still came around?
