Post-Grad Certs How Many At Once?

1 I got my first job a few months ago. I do part-time private care 2 days per week for a pediatric client but it is not where I want to be for a variety of reasons. I am well aware of the job market in Eastern Ontario right now, and at this point cannot relocate, so I am trying to make the best of everything by enrolling in post-grad education to plump up my resume and gain some specialized knowledge. I will do this while I keep hunting for another position. If I can't find anything by the time my lease is over, I feel like having this certificate on my side will help in my job hunt when it is able to expand to anywhere/everywhere.

I am wondering if anyone has ever worked towards 2 post-graduate certificates at one time? I am looking into programs I can complete online from home. I figure if I am doing 2 courses at time (so that would be 1 course from each certificate), and I only work 2 days a week, I can handle the work load of working towards completing 2 certificates simultaneously. What do you all think?
