Does any one else have kids with IGG deficiency or IGA deficiencies? Apparently my son has both. But he hasn't had any chronic infections or any issues. They are going to check him again in 3 months. I feel bad for him. I'm going to become the hand washing nazi and idc what anyone saids about it. I don't want my son to get something his poor body can't fight off 😟he just has croup though and he seems to be ok after that.. So that's a good sign.
