We recently had 2 (from our unit) train as car seat techs, and they are available at least once a month on a Monday for the whole hospital and community. I try to refer parents to bring their car seat in on that day (at some point between them becoming less scared of their baby and the rush to get out the door so that they can, hopefully, absorb some of the information). I make the parents strap the baby in for discharge and will make a comment if the straps are too loose. Usually, we do the car seat tests in the middle of the night, and the parents are not around - we have to move the straps ourselves in order to do the test properly - we should probably get the parents to do that at some point before the test (something to look into). Maybe you could look into community resources for car seats and see if there are programs for you and some interested colleagues to attend and become certified;) Make sure you look into costs and such. If your hospital is willing to pay for it, you may have to be available to serve the whole hospital, not just the NICU.
