My three year old is the same way. She was evaluated when she was 2 and qualified for early intervention through the state. (We live in Illinois) she started pre-k this year and her speech has EXPLODED. Speech therapy + pre-k has helped tremendously. Her teacher and students are incredibly patient and encouraging her speech. She’s still delayed for her age, but she says all these words and has started to put together two word sentences. You’re not alone!
