toddler still wake up in the middle of the night

My girl is 16 months old and sttn since she was 2 months old. Cannot even dream feed her. However, there are still some times when she will wake up and cry. Usually when she is going through a period of development or teething. Not sure if it helps but I have started to remind her every night that she need not cry if she wakes up halfway at night. Just hug and pat pat her chou chou pillow and go back to sleep. Mummy will come wake her up when it's time to wake up.
