How can I get baby to sleep through the night?

How can I stop my child from waking up in the middle of the night? she is 8 months old and having issues staying in her own bed…we had her in my room for the first 4 months in a bassinet but she quickly outgrew that and I did not want to make that a habit…any ideas? she seems to wake up to want a bottle…or is this still a normal thing at that age?
