Cocklodger Tbh, do what is best for you.
I exclusively breastfed my first child for 18 months and never expressed. I exclusively breastfed my second for 18 months, but started to express after 7 months.
I was fortunate in that I had no issues after the first 72 hours really and a very plentiful supply.
But I still received criticism. Not from strangers, but from family. Comments included:
"I think she's being really unfair BF because we want to have a go at feeding her" (exMIL to exh)
"She's bloody selfish doing it, that's what she is" (exFIL)
"Yes, yes, we get it. Don't you think you've made your point now?" (my mother after 6 months)
"You're not still doing that are you?" (Dad's wife after a year)
Oh and the scbu nurse who said, "if you start all that business now, you'll be doing it in the night too". Well, er, yeah, don't all babies need feeding somehow?
Enjoy your baby and welcome to the world where Whatever You Do Will Be Wrong. People love to criticise mothers of new babies, largely because they consider themselves to be the experts and you to be the wet behind the ears newbie. I think it irritates them when you make a confident decision about anything to be honest!
