Good question. There are options within the military. One option is you go on base for everything and to go off base you need a referral and those are usually just done if the base doesn't have a certain practice/doctor you require. That option is free, technically taken out of pay each month like other insurance companies, but free at each visit. The other option is you can go off base for everything and pay relatively small co-pays at each visit. I have a toddler and we chose the on base option. We moved to our current location when she was 5 months. She was seen at 6m, 9m, 12m, 18m, and 2y. She will be seen next at 3y unless something arises of course. I am sure each base has a different way of operating but here with each visit we have to fill out a developmental survey and they take those seriously. If the child seems to be progressing slower than average they put them in some sort of therapy. They also take their statistics very seriously, for instance, there was one month (I think her 9m) where her weight % was very low and they were concerned and said if it isn't up at her next appointment then they will need to refer us to a nutritionist. My daughter has always been petite but her weight to height ratio has always been good for her smaller stature. This one month I really think they messed up her stats some how as she ate like a horse until she was a little over one lol. Her next appointment she was back to normal stat wise. Anyways, I digress, the point was to tell you the options and state that our base here is very in tune to the development of children at all levels. Although they never reminded me, I had to remember and call about a month in advance to make sure I got a spot...very very busy here! Then again, if I had totally skipped maybe I would have gotten a reminder, don't know because I made sure I was on top of it.
As far as the military not being in the know about the legal issues surrounding Jenna and her children, it depends on communication. I can't see the CID (?) standing by idle while they knew of issues so my guess is they didn't know. That is JUST a guess. If they didn't know it was due to lack of communication either from LE or CPS. If they did know then they themselves should face charges as well, JMO. I know if it was here in my husband's OSI unit, they would see if they had a prior case open and if they did, whoever had that case open would be investigated to see where it failed on their end.
Hope this helps.
