let's be real, the first 2 years, you probably won't skate much. Depending on how much the baby lets you sleep.
Once they are over say, 6, you have so much more time, cause they start being independent.
I'd be a mess without my sons I think. I always wanted kids cause I wanted to experience that biological connection (I was adopted). and yes, it's so much work and responsability. But the rewards are just as huge.
