I watched the vlog too after all the comments about it which has probably pushed her views right up this week! One thing I noticed, aside everything else people have pointed out, is that when she talks directly to 'her' it's like she's talking to another adult. I know this is probably not true of everyone, but I feel most of us change our voice when talking to children, especially babies/toddlers. Your intonation changes, you generally sound more lively and interested, particularly with your own children. Lily sounded flat, uninterested and bored talking to her child.
