advise! My almost 9 month baby won't sleep throughout the night!

I breastfeed her every 2-3hours throughout the night. Sometimes, I let her cry it out but it doesn't work. She sleeps in her crib but in my bedroom. I have a routine with her, 7:40(bath time), 7:55(nurse her), and by 8pm(she's seeping). After that, she wakes up every 2-3hours. She usually wakes up at 7am. I just need some advise or try new things out. P.s.... i have tried giving her rice cereal and formula milk before bedtime.
