This is probably slightly unfair of me as, in general, PILs are pretty supportive of me bfing, despite their evident wish that they could have a greater role in feeding DDs. However, there are always a lot of comments about bfng and although I am working on letting them wash over me, some of them really wind me up!
MIL never did it herself - she had her babies in the 60s and was fed the prevailing medical view at the time about formula being nutritionally superior. Although she no longer believes this, I think that it may have coloured her view about bm quality, because she and FIL make frequent comments about my milk being too rich (e.g. responsible for her infant acne!) or too 'sour' (FFS!) and responsible for her evening grouchiness! FIL also frequently questions whether the milk i produce is nutritionally adequate.
I shouldn't be personally offended, I know, but I can't help it! we are a close family and see a lot of each other, so i get a lot of this. i wish there was a way of shutting them up without appearing as if have a chip on my shoulder about it.
