DH and I noticed that Allison didn't babble about a week ago. She blew raspberries and yelled, but wasn't using any consonant sounds. So (and this would be totally embarrassing to admit if it hadn't worked) I started showing Allie a couple of videos of babies babbling on youtube each day. Today, she's babbling. I think she just didn't know what to do!
Or she's just developmentally ready now and I wasted a fair amount of time watching nonsense talk on youtube!
