You don't say how old your children are or how old you are so its kinda hard for me to give advice but I will tell you about my experience.
I got my BS in Special Education before I got married the 1st time. Had a dd who is 17 now shortly after I got married. I was divorced when she was 3 and was a single mom until she turned 15. As a matter of fact, her 15th birthday was the day before my dh & I got married. I worked full time (had summers off - I teach) and coached until she turned 10. I decided then that she was old enough for me to spend the time it would take to get my master's degree. The only way to make more $ in education is to get more education. And I really needed more $. My dd's father has never consistently paid child support. Right now he owes me many thousands that I will probably never see. I quit the coaching so I would have time to go to school so I could move up on the pay scale. I also wanted the intellectual challenge (not that it really ended up being much of a challenge...more like a hoop to jump through).
So, I enrolled in a master's program and went 2 x per week to class. I had LOTS of homework so I spent a significant amount of time at home studying and doing homework. Dd went with me to class and hung out in the student lounge doing her own homework, playing with her Game Boy, listening to music, drawing, and writing. Some professors invited her to sit with me in class & she enjoyed that! Made her feel very grown up. Dd seemed to do fine with what I added to my load.
After earning my master's degree in Educational Administration (Urban Leadership) in '97, I was encouraged by several professors and my advisor to get my Ed. Sp. (Education Specialist degree). These hours would also go toward a Ph. D. in Education if I decided to continue on. I got a dual Ed. Sp. in Special Education Administration and Personnel Management in '99.
In '97, I took a much higher paying position as an Assistant Principal. It is the hardest job I have ever had. I worked 60+ hours per week and had to try to keep teachers & parents happy, as well as my very emotional principal. I worked for a principal who didn't want to be the bad guy so the other Assistant Principal and I had to do all of the bad guy stuff.
I found myself crying on the way to work quite often. I didn't feel comfortable being the bad guy with teachers or with students. Every single day was quite stressful and there was always something "bad" that needed to be done. I would see approximately 15 students per day on behavioral referrals. Teachers at that school did not think they needed to take care of behavior problems in their own classroom. They referred everything, including kids coming to class without materials, to the office.
My dh had never had children and always wanted to be a dad. We talked about the age issue (we are in our 40s) and decided that we wanted to try to get pregnant, regardless of the age thing. But, I knew I would have to alter my career path to do so.
I quit my job and went back to the classroom. I am the special education teacher who collaboratively teaches science with 2 different regular ed science teachers at the high school level. We share the direct instruction duties and I modify curriculum & tests for special needs students so that they can be included in the regular ed classroom.
I currently am very happy with my situation. We were able to get pregnant so we have a beautiful 6 mo. old dd and I can keep a close eye on my 17 yo dd because she attends the same school at which I work. I have good vacations and summers off. I don't mind putting the administration career path on hold since I wasn't much liking the Assistant Principal job, anyway. I'll get that Director of Special Education job that I want when our little one is in upper elementary school.
The only downside to all of this is that all the $ I had to borrow to get the degrees has to be paid back and I don't have the higher paying job anymore that would make it easy to pay it back. My loans are on a forebearance at the moment because of my maternity leave and a medical issue with which I am dealing. But come noext July, I will either need to go back to finish the Ph.D. so I can defer them some more, or start paying them back (given my medical issue is resolved by then).
I guess my message is this (and I think this quote is from John Lennon) "Life is what happens to you when you are making other plans". My path in life seems to have taken so many different directions, many of which I had never planned for, and I continue to be enriched by them all. You just never know what is going to happen to you around the corner.
