M.S.
Make sure your child is getting enough sleep and food during the day. Food intake and not enough naps during the day is often related to night wakings. Our little girl is also 14 months and we give her milk from a sippy cup when she wakes and then breakfast. She naps 9-10:30 then she gets milk and lunch then naps again 2-3:30. Snack in afternoon and then milk and dinner around 6. She goes to sleep by 7:30 and we don't give any additional milk or food after that. Sometimes she wakes at 10pm but we give her a pacifier and soothe her back to sleep. It's difficult to get them to sleep through the night but if you work on the day time schedule that should help. Good luck!
