Baby food

My son is 5 months old. He’s been exclusively breastfed but We started stage 1 purées (beechnut brand) a few weeks back and at the beginning we were feeding him a tablespoon or 2 once a day everyday. We kind of slacked off and now only feed him a the same amount but only a few times a week since I know it’s not as important as breastmilk. But At 6 months (In a couple weeks) I don’t know how many times a day I should be feeding him solids and if I should just move on to stage 2 purées or if I can feed him real food that me and my husband eat. I know this may sound stupid but I’m a first time mom and I’m a little lost on how and when to start foods. Any advice/tips would be appreciated!
