re: do I have to..

Do you try feeding her something a little more filling before you put her to bed at night???
Cereal or a peanut butter sandwich maybe??
If her tummy is full she probably won't get up as much, if she gets up at all..

Quoting Aries Baby:“ she will go to be aroung 8 drink the bottle with the formula mixed in.. and 1/2 of the normal milk bottles...then ... [snip!] ... normal milk bottles...then around 2 she'll have the other 1/2 and around 4 of 5 she drink the last one..and get up around 8 830”

I give Josephine 1 tall sippy cup full of whole milk in the morning and one in the afternoon...and for dinner she gets water..
she also sleeps through the night, has since she was 4 months..she gets a good 12 hours in ;)

oh I also put a water sippy cup in her crib because sometimes she will wake up thirsty and she has the sippy cup there ALSO I put some toys in her crib  

that way she is happy and lets mommy sleep.

try those things.
