Working & being a Mom

Nothing much has been going on lately. That's really a good thing,i t's been a long while since things have even been close to what normal use to be for us. I am scared and excited all at the same time. A job has opened up where my husband works, that would be great for me. The only thing I am really nervous about is my kids. I haven't worked since I have had kids, all these years I have been here for there every need. If I get this job my kids would have to be at home for a while by there selves. It wouldn't be to bad during the school year, it's summer time I am worried about. I'm scared they would kill each other. lol. The oldest will be 1 5 in Sept. & and will be going into high school, the youngest will be 9 in April. In the middle of them is my 12 year old daughter. I not sure what to do. I know that during the summer they are not gonna want to be stuck here until 5:oo everyday. I really do not know how working mom's do it.
