Is your baby suffering from colic? Gas? Indigestion? Try Dr. Brown's Options bottle. With its innovative internal vent system, it has provent to reduce colic, help with digestion/feeding issues and even preserve vitamins in milk. The nipple venting creates a paced flow, and provides a feeding experience similar to most nipple-vented bottles. Options bottles fit most breast pumps, and are BPA-free. The vent system can also be removed for when your baby is more mature.
