Life threatening asthma
As a child myself, when I was younger, I’d constantly be sick, had pneumonia a few times (ended up staying in the hospital for what seemed forever in kid weeks) still have a really bad immune system till this day.
Carson would keep me company, (sorry buddy for sharing this) I was really into barbies.... and I’d be confined to my room if someone was sick in the house. I remember one time, Cody was sick, Carson stayed with me pretty much the whole day and sewed and made Barbie outfits with me. That’s the kind of brother makes Barbie clothes with you? An awesome one.
