Glass Nursing Bottle for Hospitals - Milk Realization I bought this, thinking it would be useful until my breast milk supply was established, but I didn't need it after I was discharged from the hospital because my milk came in while I was there. Since the amount is small, it doesn't get hot to hold, and it cools down easily, so it's recommended for those who are supplementing with formula, as it will naturally reach the right temperature during feeding. There are two SS size nipples and two S size nipples (unused). I purchased the bottle for 2780 yen and the S size nipples for about 900 yen.
