Baby refuses bottles

Carly

My little boy is now 7 months old and refuses to take a bottle or a sippy cup filled with milk. He used to take a bottle until about 4 months old, then he suddenly started refusing. He didn’t always get one every week but seems to have developed a preference now. I’m not able to leave him longer than 2 hours at the minute, I go back to work soon and a bit stuck for ideas of what to do. Does anyone have any suggestions? Thanks!
