stringing 3 words together?

I think I read somewhere that at 24 months, most babies are stringing 2 words together, and some even doing 3. Tonight while I was getting the girls ready for bed, I couldn't locate Thing 1's PJ shirt. I asked them both to help me look. Thing 2 puts her hands on her cheeks and said, "Oh no!" Seconds later she found the shirt. "There it is! Here you go Mayee [Mommy]!" she told me. Stringing 3 words? Phooeee. We go straight to 7. I'm just sayin'.
