Just thought I'd throw in my two cents ... whilst I don't have a bub with one kidney, my DH's nan has lived with one kidney all her life, she's ridden horses, had accidents and lives life to the fullest and it's only just starting to give her hassles now ... at the ripe old age of 84!!! And it's not even her kidney that's giving her grief it's the duct leading away from it ...it's narrowed a little and needs a stent put in.

I'm sure your baby will be just as happy, healthy and adventurous as our beloved nan!
