Don't play with her at night. If you do it a lot, she's probably associating nighttime with playtime, which you don't want. When you go in with her at night, keep all of the lights off, don't smile or play with her at all. Give her a bottle or just rock her until she falls back to sleep.
Have you tried to put her to bed earlier? I know on nights that my son gets to bed late (he's normally in bed between 7:30-8:00) that he wakes up earlier for the day and is just less rested.

That being said, DS still wakes up at least once a night to nurse. He's 10 months old.

My son is 15 months and he wakes up sometimes during the night thinks its playtime.

You might want to cut out cartoons. That's a lot of stimulation right before bed.

my 8 month old wakes up almost hourly some nights.

Mine is 10 months and STILL up during the night. Usually at least 3 times.

my almost 2 year old wakes up once at least 90% of the time.

Making a huge shift in the bedtime most likely will not work. Try just doing a half hour at first for a couple nights, then move it back another half hour. If 30 minutes is too much, try 15 minutes even. Baby steps.

My 23 month old still wakes up at least once a night.

my 15 month old does this...
