My daughter will be 22 months soon and is barley talking. She has been able to say bye for months. We have had ball, sky, door and dog. Maybe a few others. She understands you perfectly she just does not speak. If i say go pick dolly up and give her to daddy she will do just that. If we are reading and i ask where a animal is like a fox she will point it out. I just don't understand why she isn't speaking when she understands what you are saying. I wasn't worried but my sister told me yesterday her friends daughter who is 2 is a good little speaker but they have refered her to someone for her speach. How can i improve it?
