Refusing milk out of sippy

Ka

One more thing.... my baby is refusing to take milk out of her sippy cup. She’ll take a sip or two then toss it. The minute I change it to a bottle (twice now) she drinks it all.... I’ve tried the 360 cup and now a sippy with a spout, which she takes better, but still not completely (1/2-1 oz out of 4 total) 😐
