FMLA 12 wk Leave Question

Celeste

I saw this info online:

 If you don't want to take all 12 weeks of FMLA leave in a row, you may be able to break it down into shorter blocks of time, or even a shorter work week or work day.

Is this true? So instead of taking 12 weeks all at once I could work 2 days a week until my 12 weeks of FMLA is used up... Who has done something like this?
