In the formation of questions and the use of negatives, there appear to be three identifiable stages. Stage 1 occurs between 18 and 26 months, stage 2 between 22 and 30 months, and stage 3 between
24 and 40 months.
في تشكيل واستخدام الأسئلة من السلبيات ، يبدو أن هناك ثلاث مراحل محددة. 1 المرحلة يحدث ما بين 18 و 26 شهرا، المرحلة 2 بين 22 و 30 شهرا ، والمرحلة 3 بين 24 و 40 شهرا.
In the second stage, more complex expressions can be formed, but the rising intonation strategy continues to be used. It is noticeable that more Wh-forms come into use, as in these examples:
What book name? You want eat?
Why you smiling? See my doggie?
