Did you ever think before you had children about possibly passing these things to your children? Are there any procautions you plan to take?

My side of the family has a genetic propensity for depression, addiction, and arthritis. I'm not really sure about DH's side. I think about this sometimes and will be on the lookout for them in the future. We thought about this before having children but figured since I had depression and arthrits we would know how to spot things early on. The addiction is the one that scares me the most especially when they get into their late teens.
