Is my 1 year old “too old” to be breastfeeding

So she’s 11 months gonna be 1 year In a few days. I was breastfeeding her in front of my mom and sisters and she was standing like butt in the air breaastfeeding and they wete like laughing but were like wtf ? That means she is too old to be breastfeeding. There like why don’t u lay on your side to feed her. I said I try but and crawls on top of me and like lays across me while she eats. They thought it was so weird. I’m pregnant and my plan was to breastfeed until she 2 but now I’ll probably stop in a few months because it’s been a lot on my body. :( I just hate how they acted like it was weird she was doing that.
