3 years and we now have enough hair to barely do this. I love it so much I can't even tell you! I smile every time I see it and she is growing up like crazy before my eyes! Everyday I ask her if I can put piggies in her hair and she says YES! The first day she kept saying "I want to show my piggies to Grandma Linda!" I LOVE LOVE LOVE it!! They're teeny piggies and I have to use the smallest elastics but they're still adorable.
I remember when I was excited to even see the little hairs. :)
