Check the temperature.
When I had my first baby she refused the bottle, it was too cold for her. I expressed a bit of milk and checked the temperature, I was making it hot.
Same thing with bub 3 today. I tried room temperature breast milk and it was spat out. Once I warned it, the bottle was taken easily.
All the best

This is a tricky one. Have you tried feeding your bub with a bottle? It would be interesting to see if they take a bottle off you first then work on getting your bub used to your husband doing it. Are they on solids yet? Keep at it!
