If you are meaning baby led weaning then yes that is another option - i myself didn't go for this option i went for pureed food adjusting the consistency as my little girl got olderMight be a bit late with this, but shouldn't he be eating solid food, not just puréed? I thought babies were meant to be feeding themselves with their hands on small pieces of vegetables, bread, fruit and so on.
Maybe she has made them herselfit depends on the way you’re weaning them really, baby led weaning is finger foods. Doesn’t mean she can’t make them herself though rather than jars when she has all the time in the world!
