My 14 month old daughter is really dependent on bottled milk before bedtime.how can i get rid of it?

she's making it as her pacifier. i hate to give in to her demands because she just had dinner of less than 2 hours.i 'm afraid she could have heart problems because of sleeping with a full tummy!or colic pain!but still i can't dare to let her scream and cry for it!and also i had this feeling that she might develop fixation like, pessimistic behavior, if i will not respond to her needs.please help me!,i don't know what to do.she's my first baby
