I completely agree. At the start, babies mostly just experiment and food is mostly for fun. Your milk will continue to be the vast majority of his nutrition and will continue to provide the same immune benefits. It's also perfectly fine to wait a few weeks if the added dishes/mess is something you'd rather avoid until after the flu season. An interesting thing about breastmilk is that as kids start the weaning process and cut back on nursing, the immune components actually become more concentrated. There won't be any appreciable change at 6 months but it's nice to know that as my DD nears 2 years and is down to three daily sessions, my breasts are working hard to provide as much immune boost as possible.
