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

I think she will take her own time for that. One cannot prepone this period according to what our convenience. I am sure you must be feeding her well before she dozes off, so to make things easier for you, all you can do is, keep all the things ready for her milk by your bedside. Keep an electric kettle where you have already kept warm water. So, as the baby wakes up, you can quickly make milk for her. And if she is breastfeeding, you just have to latch her. I know it must be disturbing but it is way more convenient than the bottle fed scenario. And do not worry, as she grows up, she will on her own sleep through the night and wouldn't wake up for feed.
