LD, as you suspect, there really is no "right" number of feeds for a baby at that age. Certainly until 12 months, milk is the main source of nutrition, so limiting it to 2 - 3 feeds a day is not recommended. Some babies might only have 2 - 3 feeds a day once they start solids, but if they take more that's fine - actually it's good!

When you think about it only about 10% of babies in Australia are receiving any breastmilk, so Child Health Nurses are not getting a lot of experience with older bf babies. Formula doesn't have the nutrition and immunological factors that bm does, and can fill babies up so they don't have the soldis they need. Probably the advice about limiting feeds is based on formula fed babies.

You are doing a great job with your little one. I don't think you can go wrong if you trust your instinct.
