Guardian if we die

So, I need help. My husband and I had a lovely baby 8 months ago. We are going through the important things paperwork wise at this point. We are trying to make wills. We have decided that we do not want to give guardianship of our son, should we both die, to either of the sets of parents, due to age of my in laws and the fact that my parents live in a small town. Nothing against small towns, but the school system there isn't great for kids with disablities and my son has moderately impactful vision disability. If he lived in a small town, he might need to be sent away to the state school for the blind. That is not ideal to us.My husband has no siblings. I have one brother. When I was pregnant,my brother was our first choice for guardian. However, he started dating a very nice girl and basically has not been interested in a relationship with us- he does not return texts and we only see him if my parents come into town. His girlfriend can't have kids and they are very serious, so we are assuming current patterns of interaction will hold.We don't want our son to go to someone who doesn't know him, so we don't want him to go to my brother. We do have close family friends who have two kids. Our son is a few months younger than their youngest son. They are good parents. We are athiests and they are Christian, but that is our only parenting difference. But everyone is respectful of each other, and we wouldn't mind them taking our son to church.My husband and I are leaning towards naming our friends as our child's guardian. Money will not be an issue, we are well insured should the worst happen. Are we thinking clearly about this? Any thing we should consider that you hear mising from my thought process?Editing to add, my friend works with kids with disablities, so if we die, I know she could help with my son's special needs. via /r/Parenting http://bit.ly/2ZGYeXK
