I'm still nursing my 18 month old. She rarely asks to nurse in public any more but if she asks, I feed her.
I am yet to experience a negative comment but I have always had a "smart retort" ready to go in my head, just in case!... I also take GREAT enjoyment incoming up with these and thinking through them when feeding in public.
"Euw, do you have to do that" would ideally be met with "yes, do you have to watch?"
"Can you use a cover" - "not on me but feel free to chuck one over your own head sweetie"
"Isn't she a bit old for that" ..."Not according to the medical profession, are you not too old, and the wrong species to be still drinking a cow's Breastmilk?"
"Euw, can't you just express and put it in a cup?"
"Why in gods name would I want to?"
"Aren't you worried you'll be feeding her through the railings when she goes to school?"
"No, I'm going to volunteer as a classroom assistant so I can feed her on demand until she goes to uni"
"Bitty"
"Awww is that what your mother called it with you? My LO calls it 'boo'"
"That's disgusting"
"What is? Caring for my child? You poor thing!"
...like I say, never received a comment. My resting bitch face is clearly too good 😉
