breastfeeding rant..

when I have anyone watch my 6 month old I always pump breastmilk for her. she was eating 3-4oz which some people don’t think is enough.. (they have never breastfed) so a lactation consultant told me 2oz of breastmilk and baby food is good for her since she’s started solids. I went to go bring her to my mom and she kept saying what is this she needs at least 4oz then baby food.. when everyone on here agrees that 2-3oz is just fine… i’m so annoyed with everyone and their opinions.. so again is this ok? also she’s eating every 2 hours still and at night as well..
