I'm really struggling to get my daughter to take a bottle. She is breastfeed and I tried to introduce a formula bottle just after 6 months so my husband could help with the night feeds. She just chews on it and smiles. Ive expressed milk into a bottle does the same thing. We have done this on and off and she's still doing the same thing with a bottle. I've tried 3 different types of bottles and had different people try feed her. She is now 9 months and I'm going back to work soon I'm worried. Any tips would be amazing
