If its only once I wouldnt fight it and just make her a bottle
My baby also wakes up once around 5ish for a bottle and then settles straight away. Got to be hunger xx
She does wake more than that but that time she wakes she won’t go back down without milk. I did give her milk and she slept till 8.30 but I was under the impression that she doesn’t need milk after 6 months as that’s what the health visitor told me so I’ve been trying to knock it out but if that’s not the case then I’ll just feed her as it will obviously be a lot quicker and easier x
if she’s only waking up once a night and won’t settle for anything else, it could purely just be hunger. babies are designed to wake for night feeds so I wouldn’t try and drop them until she’s a year old and then no longer needs formula/breastmilk. i know it’s tiring... my baby is around the same age and still wakes up multiple times in the night.
