......biking! I just bought the below toddler bike seat for my bike and LO loves it. I've had it for 3 weeks now and we ride almost every day. No more fighting to put her in the carseat or stroller for a quick errand cause she lights up when I make the sign for bike. It's an awesome way to kill 2 hours and tire her out right before nap time. Our city is also super bike-friendly with lots of green belt so we're slowly exploring all the parks and sights in town. Can't recommend it enough (the WeeRide seat is also awesome).
What's your favorite thing to do with your LO?
