Need advice on training a 2 year old?

my daughter will be 2 in a week.she will not get off the bottle.i just kinda got her off her pacifier but she will not go to sleep without a bottle of milk.i have even tried just a small bottle of water and she will wake up and scream till she gets her bottle.whenever i give her a sippy cup she will either not touch it or she will put the juice in her mouth and always spit it out .Also lately when she wakes up she is completely soaked.its almost like she gets her diaper drenched in just 30 min.i constantly have to change her through out the whole night.i really wanna get her off the bottle because im pregnant and wanna train her completely before this baby is born.does anybody have any advice on what i could do?
