My son did the same thing at about 8 months. Once he started eating table foods, he just didn't want the bottle anymore. Here are some things I did to make sure he was still getting the nutrients of breastmilk or formula.
1. Try giving him his breastmilk or formula in a sippy cup.
2. Mix formula or breastmilk into things like yogurt, mac and cheese, oatmeal, cream of wheat, applesauce...anything that you think you can mix it with. If you're using formula, you can just mix the powder right in to most things. If you're using pumped breastmilk, replace water or milk with it. Or use less water or milk than is called for and thin it out with breastmilk.
Like I said, my son did the exact same thing. He just nearly refused to take a bottle. I kept offering it a couple of times a day and sometimes he'd take it. But in reality he just wanted to eat what we were eating. He wouldn't really even take baby food that well. So I started giving him soft things like pasta (whole wheat) and peaches or pears. His favroite veggies were green peas, soft green beans and he absolutely loved chunks of sweet potatoes...I would sometimes mix them with butter and sugar and cinnamon! He loved macaroni and cheese (even with formula mixed in). Yogurt was a favorite too ( I bought the Yo-baby brand that has fruit and baby cereal in it). He self-weaned at 10 months old. I of course freaked out, but his doctor said to just be sure that he was getting a well balanced diet and to go ahead and start with whole milk. He's 18 months old now and is the best eater. Good luck! Just be careful to introduce things one at a time and make it good, nutritious stuff and I'm sure he'll be fine.
