My 13 month baby still wakes up for night feed. How to get her to sleep through the night?

You can try to feed more during the daytime to make sure baby is fuller during night sleep. Normally my kids will tend to wake up for night feeds. if didn't eat much during daytime. If you are doing latching, it is possible that baby is looking to suck for comfort. 13months is the age when baby feeling high separation anxiety.
