I think you need to rethink getting a motorcycle till your little baby is gone from the nest or would you rather have an accident while you are riding a motorcycle with your kid seated behind you.
Accidents do happen, my dear. Even with motorcycles. Have you ever seen a road rash happen to someone? Think about your child getting road rash or worse being killed by an accident that happened to you and your motorcycle while on the road.
Do you even have leather motorcycle gear for your kid? If you don't, think about spending hundreds of dollars getting specialized gear for your child each year as they grow. All that money could be spent on things that would be good for your family - like food, rent, clothes and books for your kid to read.
If you want a motorcycle, please think about waiting till your child is older, till then, get a car.
