Crew saying "baby"

Crew has really started to talk. I can't believe at only 10 months, how much we can already understand what he is saying. Last Friday I was reading him a book before bedtime and it kept saying baby. I would say baby as I read the book, sign baby, and tell Crew he is a baby. Once I put him into his crib, he started saying baby to me. It was the cutest thing ever! I couldn't help but record it. He says it so clearly! He now says: mama, dada, baba, pop, papa, and baby. We love to hear him talk!
