We use Avent bottles and, while there was some dribbling in the beginning, once our DS started latching-on well, we started getting the froth. (He sucks down his bottles at about 1 oz/min and never comes up for air!) But we also get a good head on the milk if we mix the water and formula powder in the bottle, just before a feed. If you want to eliminate the froth, try adding 2-3 drops of anti-gas drops (simethicone) to the bottle, before you feed. The drops didn't seem to help in the usual way, but they do get rid of the air bubbles in the bottles.
