A good reply by snojones. Especially, "be patient and persistent." Learning guitar is not a race, it is not a competition. There will always be someone who learns faster than you, there will always be someone below your level.
As for calluses; my opinion is that they build faster with an acoustic,versus an electric guitar. Of course, there's more 'discomfort', i.e., electrics are generally considered easier to play.
As for baby sitting; an [u]unplugged[/u] electric guitar could provide some quiet practice.
Good luck. Most importantly, have fun.
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
