Many of the women I know, myself included, spend their twenties and thirties struggling to live up to the ideal of having it all. When it's physically ideal to have children, most of us are off concentrating on other things: travelling, establishing careers and looking for that person to share it all with. Your twenties are really the time, if not to act, then to consider and make crucial decisions about what you want your family and future to look like. Instead, most of us defer those decisions, not realizing how fast time flies.
Most new parents will understand that it doesn't happen overnight when you have a baby. How did we get to this point? A decorated home stays intact with a newborn. It's once that babe gains some skills that you may need to rethink your home as a whole and get down to the brass tacks of baby-proofing.
