Math fist or Reading first?

Hi,
I have been doing a lot of reading about doman’s programs and wanted to start it for my 10 month old baby. I did start it some time back, but could not continue it. So, wanted to resume it now.

Starting it afresh, what should I start first , math or reading?
How should I start it? What should be the number of cards shown per day? and what should be the schedule?

I am a working mom and I spend most of the day at office, so, please help me with the schedule and routines for working moms.

Thanks
P
