part time or full time???

I've been teaching part time since Brooklyn was born and I've loved it. I've taught AM Kindergarten for the last three years and it's great because I get my own class, I'm home by noon everyday to spend the majority of the day with my kids, and I get a chance to get out the door and have a few moments of grown up time everyday (even though most of it is with other kids, it gives me a sense of purpose and provides a little challenge). I've enjoyed having the best of both worlds - being a mom and having a career. Now that child number two has arrived I don't know what to do. All along I've been planning on continuing on with AM K despite the fact that I'll only bring home a ittie bittie paycheck after daycare and gas to/from work everyday. Besides doing the part time thing, my other obvious choices are working full time or staying home. I have to admit that staying home scares me because I think that being a mom is the hardest job in the world and sometimes I feel like my job gives me a bit of a break and a reason to get out of the house, plus my own identity. I give props to all the SAHMs out there....I think I would drive my husband crazy. Anyway, my other option is full time and could potentially be offered to me since my school ended up with more kinders than anticipated this year...very tempting financially since it is double the paycheck without really double the work and since childcare costs are basically the same. But still....my babies are young, Grady doesn't sleep through the night, my husband doesn't like housework....how do working moms do it? So with all this said, I'm a bit nervous for the school year to begin. I like to be in control, but am trying to give this one to the Lord....knowing he will provide me and my family with the choice that is best for us.
