These are the brands I tried:
The ones from neonatal care (no brand lol they gave us heaps when she was in hospital)
Mimijumi (showed promise but no luck)
Pigeon narrow neck
Closer to nature
Bbox sippy cup
Closer to nature sippy cup
Nuk sippy cup
She likes the nuk bottle and sippy cup so I suspect it's something to do with the softness of the silicone teats and also the flow. Nuk was the last brand I bought. I tried it and she just bit it at first which was progress as she wasn't outright refusing even though she wasn't sucking. Then last week she was sucking her thumb and my BIL said she's wanting to suck why not let her suck the bottle teat so we just took the teat out for her to play with and she put it in her mouth and sucked away. We were astonished. So tried some water in the bottle and she sucked. I've tried 20-30ml of either water or ebm a few times since and most times (not every time) she's taken it. Today I gave 30ml water in the nuk sippy cup for the first time and she also drank from that. I have childcare orientation Friday so planning to take some ebm to see if she'll take it from them.
Maybe take the teat out to play with like we did? Not sure if that helped but worth a shot?
