I wouldn't put rice cereal in her bottle. I have read that doing this fills up your baby but doesn't help them to recognize when they are full and to stop eating and that this leads to problems later in life with child obesity because they don't recognize that they are full and to stop eating. I read this on an Enfamil web-site, I signed up to get newsletters that match my child's age. I have a 5-month old daughter.
I would suggest feeding your baby some rice cereal before bed along with the bottle. You could also try increasing the amount she eats in the day, she could be going through a growth spurt. Babies will let you know when they have had enough to eat, they will get bored, push the food away, or turn their head away from the food.
Or she may be teething and wants something to suck on to sooth her back to sleep, have you tried a pacifier?
She may also be ready for a bed time routine. About an hour before bed you start your routine, give her a bath and let her play in the tub a bit, then give her a baby massage as you put her lotion on, to help her relax, then dress her in her pjs and read books until it is time for bed. Keep the lights dimmed in her room while you do this to keep a relaxing atmosphere. This is gives her time to settle down and get ready for bed. This is what we had to do when my son was around 1 year old and we decided we wanted to start weaning him from his pacifier. It worked great and we only had to keep up the routine for a couple months. You can see what works for you because some nights we got home too late to do all that and would just read him a story and put him to bed.
If you have questions about how much your child should be eating during the day call your pediatrician. I know that mine has a formula that is based on the baby's weight about how much they should be eating.
That is rough, not getting a full night's sleep...Good Luck
