DS is 3 months and bottle fed. Have been using Playtex Nursers with the slow vent nipples that came with. He eats 5-6 oz. per feeding. Sometimes he drinks it in 10 minutes, other times 30 minutes. Its not an issue for me at home but his daycare provider mentioned it because obviously isn't conveinent for her to spend 30 minutes feeding him with other LO's to tend to. Any pros or cons to nipple flow? If it matters, DS has horrible gas and is on a soy based formula.
