This weekly design tip is for all present or future parents. Feed your baby with style with self-warming bottle Iiamo, designed by Karim Rashid. It is designed with an easy, place-push-and-play mechanism. Generaly very easy to use. Pour in milk , activate the cartridge and within 4 minutes you will have body temperature milk ready to serve, no matter where you are. This portable bottle warmer uses a simple chemical reaction between water and salt to heat the bottle. Liquid inside the bottle is warm for around 20 minutes. Iiamo is completly free of BPA, parabens, phthalates, perfume and other harmful additives. The only problem I see with this bottle is that heating cartridges are not reusable and must be replaced after each use.
