Well, at the risk of being criticized, I will offer my humble opinion on the matter – if the job is low stress, you enjoy it, and ONLY 2 days a month, and you do not notice it affecting your family adversely, I would go for it!!
You can do a lot with $350a month, if nothing else, invest it for your family’s future. Also, I think I recall you are a nurse (?) and I’m guessing if you don’t work your license would lapse-? Plus, there’s such a shortage of nurses right now-what an awesome service you provide. But, the bottom line should be what affect your working has on your family.
I felt very guilty when I worked full-time and my son was in daycare for 10 hours a day. I quit my high stress, high paying job in Jan of 2000.
Not working at all was not right for me either. I finally have a situation that we all are happy with. I work a few hours a day while my son attends a wonderful preschool that he loves. My wage is fairly high (I don’t think as high as yours) because I have 15 years of experience in my field. It is expensive because there are only a total of 30 children in the program (2 classes). We get to spend much more time together but he also has a classroom setting with his buddies, playground, art projects, etc.
(He is 3). Again, whatever is best for your family. I try not to criticize the choices anyone makes, although it might not be something I would do.
As for me, I enjoy bringing in some income while my son is at a good school at the same time. I look forward to continuing this schedule when he goes to Kindergarten in 2 years, maybe working a few more hours, but having the flexibility to help at school, etc.
Good luck with your decision!
