Puggle is really paying attention to what he is saying, and regularly asks what starts with a given sound, or what sound is at the start of a word.
We’re also spending some time paying attention to how we form sounds. Since I’ve been printing the alphabet letters for him to draw on, he’s started asking what words start with that sound, or what sound does a given word begin with. And he’s been offering suggestions. Some of which are very accurate, but others remind me that he doesn’t have a complete grasp on all sounds (although, they are age appropriate still), ‘W’ for Wooster (rooster, I know ‘r’ is one of the later sounds—and in fact, he does occasionally say it correctly) and ‘P’ for bus.
