My 2.7 years old daughter can talk many almost all words of daily use like noun verbs and all but not yet started to speak in sentence yet. She can convey her needs by words. She is super active child but I noticed she is not matured as other same age group child. She achieved all milestones on time except speech. She understands every thing what we say and follow comands but when other people ask her something she ignore them and not listed to them. She weak in simple conversation as per her age.
