Do I need to cook blueberry for 10month baby?

You can if you want to but some parents opt to not cook them. They puree them raw or even chop up the blueberries and serve them as finger food. However it is recommended that you stew the blueberries if your baby is below 7-8 months and also if your baby has any troubles with digesting other foods. http://wholesomebabyfood.momtastic.com/blueberrybabyfoodrecipes.htm#h0ZVUbJrWJjRjHS1.99
