Babies and wheelchairs.

Ok so I have a condition called Ankylosing Spondylitis. Which is sort of a Rheumatoid Arthritis. It often causes the spine to fuse together over time.

It's possible or even likely that I will become wheelchair bound at some point. Especially because I developed it almost a decade earlier that average.

I want to make the most of my future children's childhood either way. Advice?
