My baby boy turned one in September

Unfortunately, he WILL NOT take a sippy cup. He is EBF, and never saw a bottle. Whenever I offer the cup or even show him how to use it by drinking from it myself, he just turns his head or slaps it away. I am hoping to wean soon, and this is really getting in the way of that! He hates cows milk, gags every time. I can't mix it with breastmilk because I never pumped. He likes water, but has recently refused that too. I used to squirt the water into his mouth with a straw. I've tried a bunch of different cups, with spouts, 360 cup, basic sippy, straw style...im thinking of trying the Latch sippy cup but I'm probably just going to wasted the $6-$8 on that because he won't use it. Any advice or support will be appreciated. This is the one thing that is really stressing me. I think once we master this (hopefully sooner than later) I can be less stressed & can go on girls nights or shopping days with friends. TIA.
Re: My EBF 1 year old, won't take a sippy cup!
We're still doing bottles 4 times a day because of it. No idea what to do!
you could try giving him a sippy with the stopper taken out. It will be a mess but it may show him something good is inside and get him to start trying. Maybe try to with small amounts of milk or water to start and once he has the hang of it tu using the stopper again
