BBB was a total disaster for our 5-year old. She was a real trooper the whole visit and we had fun taking the pictures. But after about 3-hours she burst into full out sobs because her head hurt so badly. We started walking to the bathroom to remove it, but she was so crying so loudly that I just scooped her up and ran. Trying to get the gel and everything out was not easy and caused more pain but I managed the best I could. Her hair looked funny afterwards, but she felt better shortly and we went off for more rides.
I am definitely an activist against BBB. I used to put my daughters hair up in a very neat bun, gel and all, for her ballet class. The teacher was always pleased and used her as an example of how to do it. I managed to do it without hurting her at all, ever. If I can do a good job and be gentle, so can they. But there are too many horror stories and, after ours, I can never be supportive of them.
