When my daughter was teething, she would get diaper rash and blisters so bad they would bleed. The only thing that worked was to keep her diaper off and just lay her on something she could pee or mess on. The air helped dry the blisters so they could heal. My heart goes out to you for all you have been thru. Little BabyBear has the best Mommy and Daddy he could. I'll be praying for Baby's improvement and for someone to be able to help you make him more comfortable. Oh, and welcome to YT.
