We didn't see any evidence of it, but Brenda said that Henry got up on his hands and knees today. He did use an inchworm-type motion again to move towards his toys, but we didn't catch any knee rocking action.
He was babbling basically non-stop today from the time i picked him up until he started nursing right before bed. As i've mentioned, it sounds more and more like talking. I think this is due to the mix of vowels and consonants that he's exploring.
Otherwise we had an non-eventful evening and hopefully a quiet night ahead.
