This is something you really should discuss with her pediatrician. Has she been tested allergy wise?
You need to discuss options that have enough of the essential fats crucial for brain development. That's one of the reasons whole milk is recommended until at least age 2.
You might even seek the advice of a qualified pediatric nutritionist to assist with the transition. We drink almond milk from time to time and on the carton it indicates it is not recommended for children under 2. Rice milk would be the same way. It's too low fat.
You also have the option of using a toddler formula rather than whole milk.
And if you want to stop washing bottles, you need to get little one on a sippy or straw cup. I have a formula feeding friend that has her babies off the bottle by 9 months so there is never a bottle fight in her house.
