Dr. Brown's baby bottle 270ml Dr. Brown's Glass My child tried this series of baby bottles and stopped swallowing air, which eliminated bloating. So, I bought more. I'm selling one of them because I don't use it. The box has been opened. Also, since only the slim type is sold in Japan, I imported the wide-neck type from China. There is also an attachment that allows you to use Pigeon nipples, so you can use Pigeon's Mother's Touch series nipples. The original nipple included is for 0-3 months.
