Bottle recommendations

I'm looking for recommendations on bottles. My son is almost 3 weeks old and we have a spit up problem. We've tried a handful of different kinds: Dr. Brown's, Tommee Tippee, Avent, Nuk and Playtex VentAire. We've been using the Playtex bottles for probably the past two weeks or so and at first they seemed to work okay but as time's gone on and he's eating more his spit up has increased, in frequency and volume. Although I know spitting up is going to happen I feel like it shouldn't be this much. Any recommendations are appreciated. Thanks in advance!
