hi john! sorry to hear of your troubles. i have a letter like that in my personnel file at work, as does my husband. my son was ill a good bit in his 1st 6 months of life, but lately his routine illnesses have not been any different than my other non cah kids. he does not get sick more than them either. if you don’t mind me asking, what have the issues been with your children??? i can imagine that even with routine viruses  and the like, it would be tough to trust other caregivers! best of luck!
