I was aware of the possibility of babies getting a flat spot, so from the time my girl was born, I was careful not to let her spend too much time on her back. Unfortunately she had a tight neck (torticolis) and always slept with her head to the right, no matter how much we turned it.
At 2 months I started to notice the flat spot but it was mild, pediatrician said we would monitor. I hoped it would get better but by 4 mo it was worse… Our girl started off with a 7mm difference on her head which we were told was moderate. They said we could do the helmet but it’s not a big deal and might go away.
After a lot of debate we started the helmet at 6 months. It ended up being 2k out of pocket because we have a high deductible. They said it could be 3-4 months of the helmet.
Well I am here to say, I AM SO HAPPY WE DID THE HELMET. After just one month she went from a 7 mm difference to a 3 mm difference, which is in the normal range. It also allowed us to stress less. We are going to do the three more weeks and then stop altogether. Our babies forehead also protrudes less now and her face is more symetrical. I will note we did physical therapy as well.
I spent a lot of time stressing this decision so I wanted to share my experience here in case it helps anyone
