purée baby food

Baleigh
Hey moms! My son is 7 1/2 months old and I am still exclusively breastfeeding. I have given him rice cereal recently with my milk, and also and him try baby food I.e peas, squash, bananas and apples. I just ordered the baby bullet to start making his own food. How do you moms who do it this way like it? How much do I feed him a day if I am still breastfeeding? I would love to get a little advice/input from you all! Please and thank you!
