Feeling a little anxious...

I am so gratefull.. Jodie is doing really well she gained another 250grams in the last week although she is not growing in length nor head size. I am really thankfull that she is gaining weight and I have to say she is now drinking a liter of milk per day. Since the tube has been removed she has been doing great, I am almost 100% certain her reflux is gone. There is no more coughing and wheezing and shortness of breath, removing the tube was the right thing to do... God has been so good for our family. I have to admit I am a little anxious because Jodie's speech is not really there yet. She makes noises but with no syllables such as da,ba etc, I am sure it will happen. I exercise with her 2 hours per day and have made recordings which I play over and over again, I am just a little bit frustrated because I am not able to see any improvement.
