It's pretty normal to start refusing the spoon at that age. It will be a long time before she can manage the spoon on her own (I think 18 mo is the average), so welcome to the world of finger food! You can offer her a pretty varied diet of ripe fruit chunks and steamed veggie chunks. If foods seem slippery and she's having a hard time, you can coat them with dry baby cereal or crushed cheerios. It will seem like she's eating less, but that's okay. Remember that purees are mostly water and finger foods are just food, so it will take less to fill her up but she's actually getting the same amount of food, if not more. Sometimes letting her hold a spoon can help you get some puree into her, but if that doesn't work, no big deal. Good luck!
