I am just filling my calendar with not-too-difficult stuff to do!
I'm having midwife, chiropractic, and acupuncture appointments each once per week now. Luckily, most of this is covered by insurance, so it doesn't cost me much, but especially the chiro and acupuncture feel pretty indulgent--both make me feel physically and emotionally released/relieved every time. I make sure to schedule these appts for different weekdays.
I'm getting a manicure or pedicure each of the next several weeks, which I normally don't indulge in, but they aren't really too costly, and, again, it is something nice to see on the calendar.
I'm trying to get at least one dinner/lunch out with friends (with or without kids--'cuz I actually like taking DS out with us

) for each upcoming weekend. I planned a dinner out for DH's birthday for the weekend before I'm due as well.
Even scheduling playdates on weekdays with DS's friends whose mommies I enjoy most seems like a good distraction for me, and that doesn't cost anything.
