Bottle help!!

Kim
So it's been months since my guy has had a bottle. He's 5 months now. Dr wants me to give him water but he is refusing to take bottle! I've tried sippy cup too but he won't take that either. Yesterday I was gone for a few hrs for the first time and hubs could not get him to take a bottle at all. We use Tommy tippee can anyone recommend another type that's close to a natural nipple? I have my sister in laws Bach party in a few weeks and I'm terrified to leave baby over night with Hubs if he won't take a bottle. Thanks
