I'm so confused

Snookie was fussing this morning and here is the reason: his eyes won't stay open. Yep, do I know why... haven't a clue. I asked was he sleepy and needed a nap or were they doing something he blinked or something... he had no answer. Just kept on fussing and then turned and said, "neber mind" and went back to playing. Seriously, is this kid on drugs and I don't know about it??? Three year olds are so weird.
