When you find out the hottie you just met has adorable kids, it becomes up to you to bond with the offspring of your beloved. Most likely, you will win over the heart of the single parent in question by demonstrating your super winning (step-)parenting skills. This may be a step in your plan for Romancing the Widow.
You may also become a Parental Substitute for kids whose busy single parent doesn't always have time for them; it's not always about getting in the parent's pants, it may also be a sincere bond with the rugrat in question.
Probably a good way to prevent Blended Family Drama.
