Jackson has started to say "mama" and "dada". Sometimes "mama" sounds like "mum" and "mmmama". He just figured out how to open his mouth when saying "mmmm". He says "mama" when he's more tired and then "dada" when he's happy. He's been saying "dada" in the morning a bunch lately. He says it with a high pitched voice.
I helped him figure it out, but now he can do it by himself as long as the giraffe is there.
I think this is his first actual crusing along something. Before he would be standing and get down and crawl and then stand back up again, even on really short distances.
