I have an 11 month old baby and she wakes up thru the night more then two-three times for formula is this normal ? shell be one soon.

No: You need to wean the night bottles definitely as soon as possible. She will get cavities from the milk at night!

Pattern feeder: As long as you feed her at night she will follow a feeding clock that wakes her up to feed at night.If you drop the volume gradually and move to only water at night, she will replace the lost calories with more day feeding.At some point she will stop waking to feed, but might wakee for comfort/contact.If you let her stir/fuss foe 5min before you check her, she will quit this.

Try feeding: try feeding some solid like rice and fruit about 2 hrs before bed and when baby wakes up at night only give her water in the bottle .specially because she may be getting her molars and milk feeding at night may give her tooth decay her requirment fo milk at this age is 16-20 oz tops per day
