I was just looking at an email from Blooming Marvelous Baby Matters which gives the following milestone advice: "By the time your baby reaches four months of age, the babbling will be much more noticeable. You're likely to notice her trying to say words such as "bottle", although it may come out more like "bobo."
This isnt true is it, I cant really remember that far back but dont think he was doing anything other than random squeaks!
