How can I wean my child from breastfeeding?

hi mamas, I’m looking for tips & advice on how to wean an EBF 1 year old. She’s never liked bottles so i never pumped. she some times shows interest in a sippy cup, but she only sucks when the cup is facing down if i lift it up to where she can get the milk out she won’t suck anymore. She will literally throw a screaming fit if i deny her the breast & doesn’t stop until i give in… it’s hard not to because i feel like she starts hyperventilating… I’m just feeling really discouraged at this point.
