Have any of your LO's stopped saying or forgotten certain words already? One of the first animal sounds DS would make was "moo" but he won't do it at all now. He's got all kinds of other animal sounds, but he just will not say moo! He also won't say hi anymore. I figure it's normal, but I just wondered if anyone else has noticed this.
Re: Forgetting words?
As far as the 3 words question, I am trying not to worry about that and focusing on the communication/interaction he does display. It's just one indicator and if your LO is meeting other social milestones - hugs, eye contact and other nonverbal communication there's probably no need to worry.
