As of today, Arya is virtually helmet free. She has to wear it while she sleeps, like a child would wear a retainer after braces. A month from now she should be done with wearing it at night. When we started this, one of their measurements showed that her symmetry was off by 13 mm. Now, she's off by 2mm. I never imagined we'd get to that number as much higher than that is still within the normal range. I tried to take an after picture of her head today, but she's a busy kid and did not want to stand still. Her hair makes the back of her head look a little lopsided, but it's not. I've re-posted her before pic here as well.
Eiley isn't as lucky as her sister. We knew going into this that her head shape would be the harder of the 2 to correct. She probably has at least 2 months left and possibly as many as 6. Each month we will evaluate how much her had has grown to see if it's beneficial to keep the helmet on or if her head is as good as it will get. At least she's making the most out of our money since the helmets are a flat fee and it doesn't change if you need a second helmet or if your child is in it for a really long time.
