Love it Marie!! Good for you for making it to 4.5 months. Many would have given up.
For a society that prides itself on being 'natural' and 'organic', many people still don't really understand breastfeeding. I guess you can't blame them...what 65 year old man is going to pick up a LLL book in his spare time

It is hard sometimes when people criticize, because you don't know exactly how much milk the baby's getting (as opposed to formula feeding). So you can't say with certainty that they got 'enough'. The wonderful thing about our bodies though is that in the vast majority of cases, a bf'ing mom
-has enough milk for their baby
-has the right balance of foremilk/hindmilk
-doesn't have overactive letdown
It's mainly about us learning to do it right, and then being confident in what we're doing.
