Colic is a common condition among newborn babies. It affects 1 out of 5 infants during their first few months, yet it is a kind of mystery. No one knows what exactly cause colic. But one thing is for sure, swallowing too much air during feeding contributes to colic and messy burping. That’s why these days market is overflowing with anti-colic bottles. Every parent wants to buy the best anti colic bottles for their newborns. But how to make the right choice when you have so many options available in the market? It often gets confusing for new parents. But when you know what exactly to look for, you can easily find the best anti-colic bottles for your baby. Here are the four things you need to look for while choosing the best anti colic bottles for your baby: Venting system There are many bottles out there marketed as anti-colic, but only a few are effective in preventing colic. Some bottles have straw-like components that fit into the bottle to prevent the baby from ingesting gas-causing air bubbles, and some have venting systems built into the nipple or bottom of the bottle. Experts advise buying a bottle with a venting system at the bottom of the bottle. This type of anti-colic bottle works well and prevents the intake of air during feeding quite effectively. Bottle material Plastic, glass, silicon and stainless steel are the most common baby bottle materials. Plastic bottles are the most famous and commonly used because of their lightweight, durability, ease of transportation, affordable price, and shatterproof capabilities. But when you buy a plastic baby bottle, make sure it is BPA free, PVC free and phthalates free so that it does not have any harmful effects on baby’s health. Glass bottles are BPA-free, last longer and easy to clean but they aren’t shatterproof. Silicon and steel bottles are light, BPA-free, unbreakable, and long-lasting, but these bottles are hard to find and quite expensive as well. Nipple material, shape and flow When it comes to nipple material, you have two options available: latex nipple and silicone nipple. Best anti colic bottles often come with silicone nipple. Silicon nipples last longer, hold their shape and do not cause allergies whereas latex nipple is more flexible and soft, but these nipples may cause allergies and don’t last long. So without any doubt, choose a baby bottle with silicone nipple. Look for a nipple that simulates mom’s natural shape. Nipples are marked with size and flow and suggested age range. If your baby doesn’t follow these guidelines exactly, don’t worry; try to find the perfect balance. Bottle Shape Last but not least; your baby must like the feel of the bottle. Baby bottles come in a wide variety of shapes. There is no thumb rule to choose the shape of the bottle as every baby is different. But still, you can buy baby bottles with ergonomic design or angled neck to make easier for your baby to hold. So these are the four key tips to choose the best anti colic bottles for your baby.
