This is the god honest truth.....my 3 month old already talks in his sleep, well not words, LOL, but he goos and gaas and he is sound asleep, it is so cute!! I hear him on the baby monitor and then go into the bedroom and he's sound asleep. He sleeps in a hammock next to our bed and I can hear him "talking" during the night, flick the light on and he is still fast asleep, LOL.
