I tried this bottle when searching for a teat to suit my baby, who has a high palate after a tongue tie revision. The long teat with the rounded end works really well, feeding is much easier, with less clicking and dribbling. The latex is really soft compared to silicon which also helps, and feels more natural. We’ve had more success breastfeeding since using these teats. The narrow bottle makes paced feeding easier than other wide necked bottles. I feed my baby breast milk and have found the glass allows the milk to heat much, much faster in hot water than plastic bottles. The glass also doesn’t bob about in water which is safer. After trying this short bottle I ordered 6 large ones which are too big for breastmilk-fed babies, the short 110ml is enough and much more convenient as they fit better in the fridge and in my changing bag. So I have saved those for when my baby is older and ordered 6 short bottles - just the glass part as the teats and tops/lids are compatible. Super happy so far!
