My 13 Weeks Baby Refuses To Take The Bottle And

My 13 weeks baby refuses to take the bottle and we have tried 6 different ones, and still no luck. She gags n scream bloody murder the second it is on her lips. I had to go back to work, but I pump and bring them the milk the fallowing day. She eats great right from me but not a bottle. Her pedestrian says she is just picky, but I have 8 kids and had no problems with them.
