Absolutely! I have been feeding from both sides, switching when my son bops off (but no sooner than 10 min, so he gets hind milk from the first side). For the most part, I've fed him 12-15 min on the first side and about 10 min on the second, although as he got older he got more efficient. FYI, he is gaining weight and moving up in percentile terms, so it must be working for us.
