I have a dcg and dcb who were slow to talk and then suddenly they were chatting away. Some kids just take their time. I also have another dcg who just turned two and doesn't speak much and when she does her pronounciation is really poor. She says uhhhh for yes, so I always ask her to say yes and encourage other words from her as well as repeating the alphabet with me. Her parents don't work with her and also slap her hands away when she tries to self feed. (a client relative told me this) Here she self feeds. So yes, I am finding alot of parents are keeping their children in the "baby zone" far to long.
