Clara's hair had a similar feature to Andrew's as an infant - she was rocking a pretty awesome rattail. Unlike Andrew's this grew out down her back. It was becoming difficult to keep untangled, and it was hard to see how it would integrate into her eventual hairstyle, so... we lopped it off.
I told Travis when Andrew was a 10 month old who looked like a hobo that you can't cut a baby's hair before they turn one. But here I eat my words.
