I'm new to this forum and I don't have UC experience but we are wanting a home birth with LO#2. You can bring LO to the pedi on base/post even before s/he is enrolled in DEERS. LO will automatically be covered under Prime for 60 days. All you have to do to get LO seen by a doctor is show your ID. Once you get a birth certificate (I'm not sure how you go about doing this with a UC, but I'm sure others here do) you can enroll LO in DEERS and choose Prime or Standard.
