I've always worn both hats.
For the first 3.5 years of my son's life his dad spent 1 day a week with him. (He'd leave at 5am, come home at 10pm and go to bed the other 6 days a week... so even though he was here, he wasn't here when our son was awake, and he never did night/stuff)
For the next 4 years, he'd spend maybe an hour with him every couple of weeks. (He'd get up at 10am-noon, leave, come home between 2am and 4am IF he came home)
For the past year he's been making a HUGE effort to be a part of our son's life. He's home at least 4 hours on the weekend, and comes home about an hour before bedtime. ((My husband decided he wanted another baby last year becuase he missed out on our son. Nope. Sorry. Not gonna happen. Spend that time with the son you DO have, don't try to replace him with a "do over". Don't get me wrong, I love kids and would have 10 in a heartbeat with the right man. My husband is NOT the right man.))
Yup. Just been me and kiddo for the majority of the time the past 9 years (well, other adults, friends, teachers -we homeschool, but kiddo has lots of outside classes-, etc. as well. But just me'n'kiddo).
Kiddo helps me cook, tear down drywall, build fences. We read, go on outings, snowboard, play basketball. I'm an active / rough and tumble person. I'm the snuggler. I'm the one who kissed his trains good night. I'm the disciplinarian. I'm the one that has to deal with puberty (sigh). I'm the one his friends come to. I'm the one who reads the manual on how to build the bike, slingshot, 50 piece "some assembly required" toy and builds them. I'm the one who designs the treehouse, heads over to the skate park (I can't skate), washes the cars, wrestles, makes brunch.
But even during the weeks we spend with other men (uncles, etc., on vacation) while they take over the moer "Dad" type duties... I'm still ME. The things I *enjoy* doing are more "masculine", by and large. Still a girl.
