I'm so sorry you're going through this, it sounds awful. I haven't had a Bub yet, but I'm relying on my Mum's support for bfing, so I imagine it would be really hard to hit a wall.

My MIL has made some comments about "not bfing beyond 6 months" as if to do it longer would be weird. I was bfed until I was almost 3, so her comments really grate on me. I expect I won't be sharing much of it with her though.

Unfortunately some people feel confronted by things that are different to what they do/did, and take it as a personal slight on their own parenting styles to see someone do it differently. Remind yourself that this is their "stuff" and you shouldn't be made to feel bad for your own decisions, even if they do fly in the face of what your parents do/did.

It's sad that you can't access support from your Mum, but rest assured there's support elsewhere (here, ABA, your DH, etc). Stand tall and leave then to their own stuff.
