Go for the job sweetie! It sounds like you really want it and it would be a good opportunity for you. It seems like you need to build your resume and this would give you the chance to add some Canadian experience to your resume. That is important long term unless you want to do daycare forever.

Go for it. YOu can always start the daycare back up if you change your mind but it might be a good opportunity for you to take the job.

I doubt you will be in contact much with your Brother in law if he works in another city. The only way it could go sour is if you perform poorly and he gets in trouble for recommending/hiring you. I doubt that you will do a bad job so take the chance and do it.

I think it is scary to leave what we know and take a chance on something new but you don't want to regret not doing it a year from now. Good luck with what you decide.
