All kids are different. Mine didn't have this particular obsession, but he had plenty of others that were equally...unique. LOL! His punctuation phase when he was not-quite 2 (I think?) was especially amusing. He even knew things like semicolons and ampersands by name. I know adults who don't know what an ampersand is called, but he'd proudly announce whenever he spotted one!

<shrug> They're all their own little people!

Going with it the way you are is definitely the thing to do. You're not nuts! I love that you have all those things up in his room and that you follow his lead.

I don't have any specific sources for you for more charts--maybe check a school supply store?--but I think keeping your eyes peeled and following your child's lead is the right thing to do.

Keep up the good mom-ing! smile
