A really pertinent question for me, since I just this week started back up at work after 4 months of maternity leave! I never, ever in a million years thought I'd want to stay home, but now that I'm actually a mom to an awesome little person, I kind of wish I was staying home.
I actually really like my job (or parts of it, at least--I'm a h.s. teacher, and while I love teaching kids in the classroom, I hate all of the administrative stuff that comes along with the job), and I'm fortunate that the school is willing for me to do part-time this year (and maybe next), but my schedule's all over the place--4 days a week, different times of the day--and then there's all of the mid-day and after school meetings, so a part-time job starts to look and feel more and more full-time. Plus, I'm terrible at compartmentalizing, so I stress about things at work when I should just be home enjoying my time with the Bean.
I don't know. I love exercising my intellect and enjoy the dynamic of the classroom, but I'm not sure the schedule, along with my own personal neurosis, means that I'll keep the part-time position I have now. I may decide to just adjunct instead, as it would allow an easier part-time schedule.
Ack. A long-winded and disjointed answer. Sorry! Blame it on exhaustion and feeling completely overwhelmed at the moment by my new WOHM status!
