Husband has the flu

My little one will be 6 weeks Monday and I’m having severally bad anxiety right now. My husband came home this morning having chills, body’s aches and a fever with a headache. We all got our flu shots in October. I was hoping we’d be protected and don’t get the flu. I’m so fucking scared of my baby getting sick or me getting sick and I give it to him. He was in the NICU for two days and I’m still traumatized from it I don’t wanna go through it again 😞
