Hi,
I got my little girl around the same age as yours. For the first few weeks, I was feeding her 4x a day: 7am, 11am, 4pm, 7pm. I did this until she was 12 weeks so at night, she slept right through and wasnt hungry. I also crate trained her. She would go in for bed around 11:30 and be up with me at 7. She is 6months now and is completely trained, since crate training helps them with the potty training. Hope this helps a little and goodluck!
