He's not ready. My 7.5 month old DD doesn't eat either. I've been trying for over 2 months. I've tried, rice, bananas, avacodos, applesauce, pears, apple blueberry, peas, and sweet potato.
Anything that comes toward her on a spoon gets knocked away, refused, tight lipped, etc... If I get it in her mouth she gags, spits, or drools it out.
What I've discovered is she wants to feed herself. I had grand ideas of making my own babyfood. I went out an bought a food processor, and she is going to completely skip purees all together and go straight to finger foods.
Just remember that solid food for a baby is not necessary. I know that everyone on the planet is on your case about your baby not eating yet. But until they are 12 months old their main source of food/nutrition should be breastmilk or formula. Food at this age is just something to play with and experiment with.
So my baby is working on her pincher grasp with Cheerios (she loves) and Gerber baby carrots, and Gerber puffs, etc.. Anything she can pick up herself she'll try. Except banana, odd, none of my babies ever liked banana.
Anyway, be patient and just try to offer baby friendly finger foods. Good luck.
