OP here - Thank you all of these kind responses. Yes, we have an appointment next week with Children's NMC (speech department) anyway because she has a lot of difficulty eating and we are in the eating program there. Your responses help me sort out my concerns so I will be better prepared for next week. I think she may recognize the word daddy and she seems to recognize the name of her older brother, whom she adores. But, other words she hears a lot like banana, bottle, milk, up, down, outside, etc I don't get any recogntion on. She's really physical, plays very well, very curious and very focused. I guess that throws this one piece of her development into sharper relief since I don't sense that it's improving. The only real change since around 9 months is that she points for stuff she wants.
Well - this has been very helpful. Hopefully, we'll have some answers next Thursday.
