The MAM Feel Good Bottle is made of temperature-resistant glass. As a result, the bottle can be heated in the microwave or bottle warmer, cooled down quickly, cleaned in the dishwasher, and sterilised at high temperature. Simple and safe to use to make everyday baby life easier. Includes MAM"s ultra soft silk teat for an easy switch between breastfeeding and bottle. Breastfeeding is best for babies. Together with our MAM Med-Experts, we have developed a silicone teat that makes switching between breastfeeding and bottle especially easy. Proven effect: Market research confirms that 94% of babies accept the MAM Silk Teat*. Thanks to its patented, silky soft surface drinking from a bottle feels completely familiar (* Market research 2008-2010, tested with 995 babies).
