So my 3.5 month old daughter has a pretty bad flat spot. We noticed it at 6 weeks and have been aggressively repositioning, using noggin nest, doing tons of tummy time, and it almost looks worse. She also has asymmetry in her face. I see a helmet in her future, but I would like to avoid it.
I said I would never get a bumbo, jumperoo, or exersaucer, but I'm thinking something where she can sit up would help. Also, I wear her in a few different wraps when I can but she doesn't like it for long.
So, what should I get? Are there developmental reasons NOT to get any of these types of seats?
