Baby still doesn't sleep through the night at 6 months.

Sydney • Mommy to Roxanne Everly Mayers, born Christmas Day 2016, 8lbs 2oz bundle of beauty. 💛 step mom to Ryko Yancy ❤❤
Roxy is almost 6 months old and was sleeping through the night from 10pm-6am at two to three months, and at the three month mark she just stopped. She wakes up at least three times a night wanting to be fed even though she eats 5-6oz before bed. Is there anything I can do to encourage her to sleep through the night?
