Is it weird?

Internationally, no, in no way. In fact in the international sense she is very young to be weaned.

But in terms of when living in a country where many people do NOT BF and very few who BF at birth make it to 6 months, let alone 12 or beyond, yes, it's probably out of the ordinary to those people.

My responses?
"HUMAN milk is better for human kids than cow's milk"
"I don't always have a cup to hand, i always have a breast to hand"
"The WHO has done extensive research and finds that there are strong benefits to children gotten by BFingfor 2 years and beyond"
"Why do i still BF? Because it's aways there, always ready and always free, why do you NOT still BF?"
