how many hours=sleeping through the night

jewelsonu

Sophia sleeps from 7:30-4:30. she is up and eats for 15 minutes and goes back to sleep until 6:30-7:30.  Is this considered sleeping through the night?  I just need her to sleep another hour to hour and a 1/2 and I will be happy. 

We don't really need to sleep train her b/c she will go down completely awake and go to sleep without crying.  She is definitely hungry when she wakes up.  I've tried letting her cry and she cried hard for an hour.  So i know she needs to eat plus with the reflux I only give her 5 oz bottles during the day.
