Toddler speech

My daughter is 20 months old, she talks a lot and has a pretty big vocabulary. The issue is that she only says one syllable of each word, usually the last one. For example, Elsa is "sa," Anna is "na," and Mickey is "key." I'm using character names because we are a Spanish-speaking family.

We saw her pediatrician a few days ago, and she asked about her word count. I told her I stopped counting after 100 a few months ago, and she said that half-words don’t count. Based on that, my daughter is now considered behind because she can’t say almost any words with two different syllables. Most words in Spanish have two or three syllables.

I'm not sure if I agree that half-words don’t count, but that doesn’t matter. I want to encourage my child to speak more clearly. Are there any activities I can do to help her? We have tried separating the syllables using toys or claps, and it only worked with her most-used word (teta/boob). I don’t know if we should be seeking early intervention because she uses a lot of words, just not the whole word.

Thanks in advance!
