Does ur SO...

So in my pregnancy I have faced a lot of obstacles, risk of miscarriage, high risk of trisomy 13 or 18, now fluid on the babies brain. My SO blames himself for all the bad things that are happening to our baby. I try to reassure him that it's not his fault, that these things sometimes happen. I feel bad that he thinks this and don't know what else to tell him to reassure him it's not his fault. Anyone have a SO that feels this way?
