My child is 2 year 10 month, he still speaks two letter words only and is unable to form sentence. Though he says 1-10 ,abcd phonetic, colours name, however I noticed that he says few words in backwards spell. Like Paani, he says pain, for sheep he says peesh, for okay he says KO .I keep correcting him. Also I found that unknowgly he pronounce the correct word but if I ask what is this he says in backwards direction. This is not with all words only few words spl which include "pa" in it.
