When asked how she likes her dinner, samantha replied, "i likeded the pizza most!" her exclamation would be best described as an example of what aspect of language development in early childhood?

Based on the use of "likeded" by Samantha, it sounds as though she is in the 1-3 year old age range. When my son was this age, it was not uncommon for him to add the extra "ed" to many of his words. This is a very critical age in the learning of the English language, and I am guessing that Samantha will soon learn to drop those extra letters.
