JDAx3: I think you hit the nail on the head for me. In comparing my boys to my nieces, I think it reinforced the idea that all children must be doing the same things. I don't think I've ever seen "Knows the alphabet" on a milestone chart, so I'm not sure when it normally happens.
Shellymos: That's definitely a cute story! It's a shame that not all stories are safe to be shared with the general public, but it's great to know they'll be enjoyed by the people here!
Austin: I'll definitely check out the Ruf book ASAP. What's the Gross book?

Thanks again everyone for replying!
