You are most definitely not alone!
Both DH and I work, and DD has a nanny come to the house three days a week, and her grandmother watches her the other two days a week.
The truth is, I love my career. I love my family more, but we also need the income! We really enjoy the time we do have together in the mornings, evenings, weekends, and holidays. There are times when I feel guilty, but this is our life and it seems to work out well for us.
I think being a mom, period, you feel guilty sometimes. I have SAHM friends that feel guilty that they don't "contribute" with the income. It's sometimes hard to find a balance. I have found peace, most of the time, with our family/work life.
Good luck in your adoption journey!
