So sorry to see that the nightwakings haven't stopped luchi.
I would definitely not give a bottle at all in her cot. I still give alex a bottle, but she has it when we read a story downstairs, that way, she doesn't associate a bottle with waking, it's part of her wind down routine.
I can't remember if you did any sleep training and what method you used.
When she wakes, does she cry? If she is happy, don't go in, leave her. If she cries, go in, check that she is ok, no poos etc, then go out, and do wiwo until she falls asleep or until she has to get up, then start her day. If she has been awake from a particularly early time, don't give her an earlier nap, try to get her back on track by sticking to her normal nap time.
If you think that she might be thirsty during the night, give her a sippy cup of water and show her where it is and she can get it herself during the night when she wakes.
