Cranial Helmet

Our little Vivi has a flat head on her back left side.  So flat, that she's undergoing the process to be fitted for a cranial helmet.  She's been such a sound sleeper since about 10 weeks old that she really doesn't move in the night.  Pair this with the fact that she's still not rolling over, and you have a child who sleeps in the same exact position for 12 hours a night which creates a flat spot.  Luckily, she's just crossing into moderate severity and won't experience any developmental issues.  Still, it's not fun to think she may have to wear a helmet to keep the rest of her head in place while the flat spot rounds out.  She'd have to wear it for 3-4 months, 23 hours a day.  :(  We've seen two doctors, including a neurosurgeon, and an occupational therapist who specializes in the helmets.  While the helmet is not 100% necessary, it would definitely fix the spot.  There's a chance, however, that Viv's case isn't severe enough to be covered under insurance and we're waiting to find out.  In the meantime, we've signed Viv up for some physical therapy to see if they can do anything for her but our first appointment isn't until this weekend.  Sigh.  I really don't know if this is something I want to put her through or if we should just rely on her hair to cover up the flatness.  I feel like the helmet is the right answer though but I guess we'll wait to see if insurance covers it and then go from there.  We should find out in the next few weeks.
