Are there absolutely no services locally that can help you? The Hospital, can offer advice on what is available. Have you contacted the local MFRC where you live?
I hate to be the harbinger of bad news, but you have better get used to the military way of life. Consider your husband's posting as an isolated posting. Although he may be in the PRTC (Post Recruit Training Center) (They still call it that in Boreden, not PAT, I know semantics, but they are different there.....), and may be sitting around doing nothing for now, a course may be able to be formed based on the amount of other candidates awaiting this course.
You have got to learn to figure out how to use local resources to help you manage you, and your family. This may be cruel sounding, but realiz, Hubby and you, have just signed up for the military. And the military will have him posted, or doing things, normal families don't do. It will now be up to you to mange the home base, and not expect or rely, on what you think should be offered to you.
Once hubby has done his training, it will be much more easier, for you to establish your family life. Until then, I suggest you tell your Mummy and Sister to start pitching in. It will be a hell of a lot easier, than wishing hubby can come and be your white knight to save the day.
Seriously, have you two given better thought to this whole, him joining the military???
