Rugrats
The show functions under a translation convention for baby talk, which is presented as essentially a separate language which only other babies can understand. The babies' dialogue is almost universally translated for viewers into comprehensible English dialogue, but adults in the series cannot understand them. One example of this dissonance is when Tommy says "Reptar!", (the title character of a popular in-show children's franchise) but his mother then responds that she heard him say "riff-raff", and that she hopes he is getting close to speaking full words, indicating that adult characters still hear the dialogue of baby characters as babbling. The translated dialogue of the babies is still presented as infantile English, reflecting their limited understanding of the world. Another major point of this plot convention is that toddlers who have learned to speak the adult language can still understand baby talk because they are at a transitional age between the two. Angelica and Susie can understand what the baby characters are saying but can also communicate with adults, though they never outright reveal to the adults that they can comprehend complex messages from the babies. Very young newborns, such as Tommy's little brother, cannot yet communicate even with baby talk, although Dil has a very limited vocabulary consisting of the words "poopy" and "mine" which are perhaps the only words he is capable of saying. The older babies, such as Tommy and Chuckie, are able to interpret what Dil is trying to communicate although, due to their own age, it is difficult. When the older babies do figure out what Dil wants or needs, it usually involves changing his diaper or giving him an object – to play with or just to experience the joy of holding it.
