For reasons unbeknownst to me beyond the fact that kids are walking Petri dishes in general, DSC always seem to be ill and under the weather with something or other. I'm talking constantly.
When I gave birth to DD 2.5 years ago I ended up in intensive care for two weeks with sepsis, I was on the brink and almost didn't make it. The organism responsible was invasive group A strep. I developed PTSD and asked for a debrief at the advice of my therapist, i asked how it could have happened and the consultant midwife said in most cases she's seen she believes it comes from young children in the household who often carry the bacterium (was only DSC at that point, it then dawned on OH that DSC did have a sore throat the week I was induced)
Fast forward to now I'm about to have another baby and have decided not to send my own DD back to nursery until after my c section as I just can't risk the same happening again. I'm wanting to isolate in a sense and take some extra precautions to not get ill. I have some complications that could be problematic (Anti E antibodies with rising titre levels, baby is at risk of hemalytic disease of the newborn) and may need to be in hospital a while longer as it is and need extra help.
DSC, however, will obviously be continuing to go to school, continuing to go between friends houses and continuing to come here. All perfectly understandable I know.
But AIBU to feel anxious around them after what happened before? I haven't said anything to OH about how I feel, how could I?
As I write this we're just getting over a sickness bug that DSS brought round, not his fault I know, but I'm just dreading what's to come 
I can't go and stay anywhere else I don't have anywhere to go and I obviously can't ban them from coming.
Please be gentle, I'm not in a good place at all. Nervous wreck to be honest.
