Verbal Signal?

Elie might have given a verbal signal tonight. I was putting him to sleep and he was 99% asleep but a little fidgety and I thought it was because he wasn't comfortable in the wrap and wanted to lie down. So I put him down on his tummy in the moses basket and he seemed like he might fall asleep, but then he started "blowing raspberries" (kind of blowing a noise with his tongue). I took him out and he peed. We'll see...
