I have a question about BLW

Amber

So we tried starting blw when my son was 6 months old. He didn’t like anything we gave him so I just figured he wasn’t ready. So we starting feeding him baby food out of a jar and water in a cup. He is now 9 months old now and I want to try blw again. I have the Solid Starts app for reference on good foods and how to cut stuff up to the correct size for his age. My question is… do I cut up stuff for the (6-9 month) range since he’s just starting out or do I go for more of his age group (9-12 months)?
