Yes, it is okay. Remember, facebook is not real life. The braggers are able to present themselves and their supposedly genius progeny however they wish.
I like the way my daughter's kindergarten teacher put things once when talking to her students about learning and ability. Some kids were learning to read, while others weren't there yet, and there had been some bragging and teasing that needed addressing. The teacher asked the kids if any of them remembered when they learned to use the potty. (Lots of giggling and snorting followed this question, but then they realized she was serious.) None did. She explained that some kids learn at younger than two, some at two, some at three, a few maybe even later before there are no accidents. The important thing isn't when you learned, she said. The important thing is that all of you learned how to do it. Then she told them that the same thing was true for any life skill, including reading. The important thing wasn't when you learned it or how fast you learned it - the important thing was that you did learn to do it. She explained that some people learn things quickly, some slowly, some early, some late, some with extra help. And the kids GOT it. They were much kinder to each other after that.
I think some adults need to hear that kindergarten teacher's potty speech. :-)
