Help with weaning baby off the bottle?

My daughter just turned 1 & has been using sippy cups since 6 months but still prefers her bottle.

Just recently we tried cutting her down to 3 bottles a day in hopes of completely cutting them out shortly.

My daughter has been throwing complete temper tantrums & refuses to take a sippy cup OVER the bottle, but I don't want to give in & just give her a bottle because it will be best for her in the long run.

Since she's not drinking as much, she has been having dry diapers which is concerning me because I don't want her to get dehydrated.

What can I do to help her transition more smoothly? Also, is it okay to let her cry it out in this instance? Thanks!
