(I thought this one was boring and forgot it, but my kid actually requested it so I had to think it up again.)
One time at school, Tabitha was reading a book.
Remember, Tabitha never washes her hair.
So little black spots dropped out of her hair onto the book as she read. She couldn’t read the book and she had to let another kid read it instead.
The Tabitha Series
Or: How My Kid Learned to Stop Worrying and Love the Hair
Since almost the time she was born, my kid never liked washing her hair. She really feared and hated it and we tried everything we could read on the Internet to get her over that.
Nothing worked until I tried these two things at once when she was almost three:
(1) I let her decide whether to wash her hair every night. I waited something like 10 days and then had to wash it. After that I was prepared to wait another 10 days, but I didn't have to. It's not so bad, kid hair doesn't get greasy like gross dad hair. This strategy was recommended by someone on the Internet.
(2) I told her a series of very short stories I made up on the spot about a girl named Tabitha who had very dirty hair because she never washed it. These stories could be at bath time or any other time. Driving, playing, whenever, so as not to emphasize and be too preachy at a time when she might be feeling self-conscious. They were in the form of stories and I presented them like any other story she might ask me to tell.
I don't recall how long it took, and I don't know which part of this was most effective. But something about this strategy worked and she stopped complaining about washing hair.
At some point I also introduced a dry towel she could use to cover her face while I wet her hair. That made a big difference, too.
After some months, she is so unfearful of washing hair that we can do it the easy way: Just put your head back and I'll get the hair wet. I carefully avoid her face and her ears. If they get wet, instead of crying in fear, now she cries in anger and I give her a towel and everything's fine.
She still requests the stories sometimes, so I suspect they had a big impact.
These are the stories in current order of popularity:
