Just got home from the hospital

We got discharged from the hospital on Sunday, the same day my husbands son comes from his moms and he has a nasty couph and I've been freaking out that my baby is going to get sick! I'm trying to not be upset and it seems my husband is taking it lightly which is pissing me off more. I feel like this has ruined my first days home with my new baby. I know I probably sound like a bitch but I'm sure any new mom would feel the same way. I almost wanted to ask if he could stay with his mom and just come back when he feels better! Ugh...
