How old will you be at each major stage in your child's life? Our Parenting Milestones Calculator can help you figure out how old you will be at each major milestone in your child's life, such as potty training, learning to drive, having a grandchild, etc.

For example, if you are 40 when you have your first baby and want to have 2 or 3 kids spaced out by at least 2 years, you might be 44 when you have your third child, about 46 when you are dealing with potty training, and you will be in your 60's when they graduate from high school.
