baby sleep

Jessika
Hello. 
Need help! So my 5 month old use to sleep from 2am-9am then wake up for a bottle then fall back asleep until maybe 12pm. Since last Sunday seems like nothing helps to put her to sleep she falls asleep and as soon as we put her down she wakes up and that is through out the wholeeeee night until maybe 7 am she knock out for the rest of the morning until maybe I0 am. Has anyone gone through this if so what helped.
