11 month old's hair

Samantha • 31 year old mommy, wife and kindergarten teacher.
My 11 month olds hair is getting wild. It's not super long or thick, but it's starting to get a little curl to it and it stands straight up in some spots. I've tried wetting it and brushing it, but it is crazy again 5 minutes later. It looks silly in a small pony because it's not enough hair and she pulls it out anyways. Any ideas?
