Homework+Baby=Too Much TV

An odd equation, I know, but my world is full of odd equations right now.
I'm currently taking 2 classes. With a 41/2 month old? Crazy you say? But I like crazy! Actually, I'm trying to get my accounting certificate so I can get a good job when I'm off my maternity leave (no word on my new application yet). I took 2 classes while I was pregnant, am taking 2 classes right now, will take another class starting in April and then will only have 7 to go for my certificate. I knew it would be a challenge, but I had a horrible bad parent moment last week.
I was trying desperately to get caught up in my Stats class, in which we're a bit behind. I'm doing better than I thought I would in it and actually enjoying it a bit. What can I say? Math speaks to my anal retentive nature. Unfortunately, Rowan doesn't know that Mom needs time to do this, so she still needs attention even when I'm trying to work. I found myself on the couch, trying to write out study notes with Rowan in her vibrating chair, soother in, watching Baby Einstein. I looked at the situation and the blank expression on her face while she stared at the TV, head lolled to the side and almost cried. I've become that parent! The TV is the baby sitter! At 41/2 months! I hated myself just a little.
Then as James tried to talk me down off the ledge, she copied the babies who were touching their noses! She just reached up and grabbed her own nose while the babies on the TV did it! It was super cute. I still felt guilty, but maybe, just maybe, the Baby Einstein DVD taught her something.
It does become a bit of a dilemma. James and I are TV/Movie/Video Game people. I don't want Rowan to watch too much TV because I think it's better for kids not to, but that becomes a bit of a challenge when that's what Mom and Dad do for fun. The TV is usually on in our house, even if we're just playing music through the PS3, so it's a bit of a concern for me. We'll figure it out. As all new parents find: you can plan all you want, but in the end you will do what works best for your family. And all we can do is our best. I know she'll be a great kid, she already is.
