We’re due to spend Christmas at my in-laws. MIL is very excited as it’s the first Christmas with two grand babies and by all accounts has gone slightly over the top with things. SIL’s 8 month old DC has just come down with RSV. Had a quick hospital trip but thankfully seems to be recovering. My husband and I are very hesitant to have our 4 month old exposed to another infant with known RSV. AIBU to cancel?
