Ya, he doees it all the time! haha It seems like it's when he's getting into a deep sleep. In fact he's laid out in his swing like it's a lazy boy right now and making the noises! lol
Chelsea's new baby, Jude, makes a lot of noise when sleeping, but nothing like your little guy. While I was laughing at the 'baby noise' I was really cracking up over his daddy's 'crying laughter' in the background! LOL
