Struggles after Maternity Leave

My vacation is almost over. I'll be back to work on Feb 23, 2009. There are things that makes me want to just stay home and there are things that keeps me hanging on to my Job. I want to just stay home for my daughter. My mom will take care of her when i go to work. Mama is kinda "old" as she says but she is just 57 yrs old. We often disagree on some issue on how we should take care of little Iyah and that's one thing that pulls me to just stay home and just take care of my little peanut. However, I also want to keep working because my salary is a BIG help in terms of sustenance and finance in our family. It'll be better for Iyah's future when I keep my job.

What do you think I should do?
