It's no earth-shattering news that biking with a baby or a kid turns regular, confident adults into super cautious and anxious parents. I become super aware of any movement and try to guess the intention of every driver before even they are aware of their next move. A slight movement to the right means they're thinking about turning right. A tilt of the wheels means they want get out of their parking space as quickly as possible. But this is exhausting, so for the most part I try to avoid busy streets as much as possible unless there is a dedicated and physically separated bike lane.
