1. After 12 months, you can take your kid for rides in a trailer (we own a Burley, which I highly recommend). You'll probably be doing different routes and times, but don't underestimate the exercise value, especially climbing hills. I take my kids for rides to food/treat destinations like ice cream shops, which they look forward to. My 6 year old is now on a tag-a-long trailer and will hopefully start riding on his own soon, or we'll upgrade to a tandem.

2. Arrange for as much babysitter/help time as possible. Use this to make time for recreation as well as errands.

3. Sit down with your wife and plan out opportunities for both of you to recreate as well as get all your errands done. Make sure both of you get recreation in. If you can share the same recreation activities, that's ideal, but if not, make sure she gets equal opportunity. Nag her if she uses her recreation time for errands - even if it's her own fault, she'll resent you for it. Explain how often you think you want to exercise and how important it is, and figure out what you can make happen together.

4. Once your sleep schedule is stable and sufficient, you can squeeze in recreational rides early in the morning or later at night, assuming you have lights. You can also jump on the bike for some errands. I've transported diapers, farmers market produce, toys, precriptions, and other items when there was enough time to spare for the slower trip speed.

5. If your preschool or elementary school is nearby, you can bike to school with your child. I often took my son to preschool a mile away from home in the Burley, doubled back to the house to drop off the trailer, and rode on to work. This spring I will be transporting three kids daily, so I can't do that anymore without a more elaborate setup like a tandem plus trailer. But 1-2 kids is quite doable.
