Michael J. Fox and wife Tracy Pollan have four children: Sam Michael (born 1989), twins Aquinnah Kathleen and Schuyler Frances (born 1995), and Esmé Annabelle (born 2001).

Fox says about parenting and Parkinson's:

“(Parkinson's) has taught me that there is not one moment that is frozen in time. There is no better example than to watch four kids grow up. For instance, I'm not feeling particularly steady right now, but this is not going to last for more than a couple of minutes. Same with raising kids. There are no moments you have frozen in amber. It's moving, it's changing, so appreciate what's good about right now and be ready for what's next.”
