I’m so sad

Ever since I given birth on November 2 my 5 year old and baby have been getting sick. I missed every holiday last year thanksgiving, Christmas and New Years. My baby recovered from RSV last week and then my 5 yr got sick and just barely went back to school yesterday. Today my baby woke up with a pretty strong cough when he was completely recovered. I’m crying. I haven’t been out of the house in almost 4 months due to recovery and illness. I was finally going to go out to a birthday party and can’t now. I’m almost debating taking the baby out like this because I need to get out 😓
