TIME...

Time to myself while DH is at work on my days off...

Time to relax after I get home from work after a 1.5-2 hour commute...

Time to sleep (nights and those naps that are sometimes necessary when you're wiped out)...

Time to get errands done (everyone always says that just getting out of the house with a child/ren is insane)...

Time to travel (funds and also once the child/ren is/are in school, we'll be limited to the school holiday schedules and summers when it's VERY hard for DH to take off work)...

Time in general as in the child/ren would have to be dropped off and picked up from a sitter/daycare/etc and that's extra time in the day...
