My lo is currently breastfed and never would take a bottle

She plays with a sippy cup (filled with water, breastmilk, or formula) and will not drink from it. I've pulled out our collection of all the different varieties of cup styles from our first, but no luck with any of them. They all end up being tossed on the ground

My plan was to begin weaning at 1 year, since that is what I did with my first, but she would take a bottle and loved cups with straws. and didn't want to bf around 10.5 mo on and I had to really stick with it to get her to continue. This one just chews the straw and then tosses the cup. Should I wait until she is more ready? Or should I just continue and hope she gets it?
Also, since it's been so long and I have no gauge on amounts with this lo...what is the average milk intake for a 1 yo?
