From the evidence gathered, it seems that this particular child has been prioritising naming things or people. This is probably because children will point to things when using 'proto-words' so that they can establish an understanding more clearly. This makes it easier for the parent or carer to try and repeat the name after them. This also makes it easier for the child to convey needs such as thirst through single words, i.e. 'juice. The parent would probably encourage these attempts to convey needs, as it means that they can fulfill the child's requirements more efficiently.
  Language can then be built around these proper nouns to establish further meaning. The child could still be thirsty and ask for 'more juice'. The parent may then wish to take this development a step further, and encourage the child to say 'please' or 'ta' when asking for or accepting this juice. As this is probably a daily interaction, the parent may feel these social words are important, and the child may pick up on the fact that politeness is important. These content words, which are usually children's first words, are especially important because of the fact that the child can, to an extent, modify them and still convey meaning. An example of this would be if a child modifies the word 'please' to 'peas'. In the right context (can I have some juice peas) the child can still effectively convey meaning as well as incorporating their own modified content word.
