Thanks so much for checking on me! Sorry I didn't see your reply earlier for some reason. I just bought some new bottles as he hated the ones I was trying and was taking in lots of air and couldn't latch properly. So now I am using the Playtex dropins with the latex teat. We started yesterday and the most he took was 40mls, then he took 30mls and finally 20mls on the 3rd try. I am offering him the bottle 3 times a day right now. Fingers crossed he starts to take it soon. Have asked for some BW vibes in another post and just needing some support! Feeling like this is never going to happen.
