Stephanie my 4 month old was doing very well with sleeping in the night and having naps in the day.

Now she won't sleep until 2-3 in the morning. She sleeps the same in the after noon for her naps. She only sleeps for an hour or less in the afternoon. And the again at 5,6, or sometimes 7 it just depends what we are doing.

And she won't go to sleep without her bottle. And I've tried to rock her, pat her butt and back, and her dad tries other stuff I even sing and hum to her.

What could I do?

Maybe you should stop letting her sleep from 5-7 pm. Start slowly keeping her awake during that time instead of letting her sleep and I bet in a few days she'll go to bed earlier.
