Don't give up, Chocolatepeanut.
Think about why you feel like you do.
Is it because you equate breastfeeding with something sexual?
It's not.
Is it because you think that the mum's doing it for her own reasons?
She's not.
Is it because you think that breastfed older children feed on demand perhaps 12 times a day and through the night?
They don't (usually!).
Or is it something else?
I'm honestly interested. If I understand why you feel like you do, I can pitch my answer to your issues, you see.
