NO, I don't think it is a BAD decision.....
Personally, I would go with alpine to get comfortable first, then go to tele. With this way you have a solid base to start from and go back to if a tele type turn doesn't work, for example if you get in to a crowded area.
BUT, I know a couple of people that went straight to teles with no problems.
On the alpine side, you don't need to MASTER it, just get comfortable with the parallel turn. May even be possible with just a day of lessons or so.
IF you go straight to tele, there are PLENTY of excercises to get you in tune with your boards (kind of like the NORM articles).
This is a great site for instructional stuff; http://www.telemarktips.com/
I will be in the same boat as you in 2 yrs or so, my daughter is 9 months old.
