No doubt I would do it.
I'm also in education Nomsie and I went back a year ago - I had the same worries and feelings that you have.
The reasons I went back were:
- massive reduction in financial stress - I can't tell you how nice it is to not have to worry like we were
- I enjoy adult interaction and the challenge was something I craved
- My career is important to me
- My DS was thriving at daycare and it gave my parents the opportunity to spend time with him too
Some things to consider; take the month job - its only a month. Its a great opportunity to see how you feel. If it doesn't work then a month will go very quickly. I also think you don't know how your DD will react unless you try - it could be amazing for both of you. And if not, it's only a month.
If it is also difficult finding work then it's also a great opportunity to get your name out there and start developing your networks again.
I agree with @tastychicken too re; babies are only babies one - yeah they are but there are lots of ways to bring up a family and it is over the course of them growing up over 20 odd years, not just in the younger years. Personally I have found the younger years great for getting back to work - my preference is to be more available during DS schooling years.
