Lisa,
I am coming into EMS at the ripe age of 43 with a 14, 12, and 8 year old as well as an active duty husband who is away for most of the year. My family is behind me 100%....well, the 8 year old did try to forbid my clinicals on Fridays, but otherwise has been pretty supportive. I just finished my EMT-B course and TN EMT-IV a few weeks ago. I am in job search mode right now, but am trying to work around the kids. Thankfully, my parents have stepped in to help when I have to be away. The kids have enjoyed learning alongside of me (they were a big help as trauma "patients") and have celebrated each little milestone, good grades, etc along the way. My husband has been incredibly encouraging - he realizes that I have found my passion. I want to go on to Paramedic school so I am sure we are going to be testing the waters with greater demands on my time. I am thankful that there are programs in the area that are flexible enough to make it happen.
Best of luck to you!
Leanne
