Ok...since this post I have not taken Logan's bottle away. He is still getting one in the evening because he is not getting enough through the nuby sipper with the bottle like nipple. He still doesn't want to hold the cup up enough to get the liquid to flow to the nipple. My ultimate goal was always to have him learn to drink from a straw because of the benefits for his speech and he doesn't need to lift a cup to drink from the straw. I worked on the "honey bear straw bottle" from his speech therapist for a week straight with no luck. (we had been trying it off and on) I was cleaning and going through my sippy cup collection (I have one of every kind there is!! Anyone need a specific kind or any special bottles you can shop at my house!) and I found this nuby straw cup that I had bought as Logan's first cup. We had never had any luck with it until yesterday. I thought I might as well give it another shot and Logan grabbed it and sucked the liquid up immediately! He surprised himself and seemed like he was shocked that something came out. His eyes got big and he continued to suck and chew on the straw. He has never drank more that a few sips from a cup before and he always needed my help. I was SO shocked that he was drinking all by himself that I think I scared Logan with my excitement! I wanted him to know that this was HUGE!! I was almost as ecstatic as when I could give him food and sit back and watch him eat all by himself. I plan to still give him a bottle before bed, because he loves it and I think he will still need a little more liquid than he will drink by himself, but he drank half of the full cup at dinner last night!! I am so proud. I don't know if it's muscle tone related, but even though he is pulling the liquid up the straw and into his mouth, some dribbles out of his mouth most of the time. I look forward to when he can drink without making a mess, but it seems like most of it is getting swallowed.
