4 oz/120ml Narrow Glass

Good glass quality and price

Good design

Excellent

This works well to REDUCE gas and spit up. This is good for sickly and colicky babies who need a little extra when feeding. I would recommend this to any parent. My baby has had reduced gas and gets more from each suckle at the bottle. The design is good and it’s actually easy to handwash each part. The size is good for monitoring how much the babe eats and gets a steadier flow of milk with less air bubbles. The beast of hold is typical like any bottle. The glass versions do a good job at regulating and adjusting temperature.

nos encantan, mi bebé los agarro luego luego, tengo 4 de vidrio de 4 oz y 4 de vidrio de 8 onzas, desde que los usamos mi bebé ya no saca tantito pedito, ni tiene malestar como solía con otros biberones, aparte de que están bonitos y resistentes, le funcionaron a la perfección para sus cólicos, los amamos.

My only choose of feeding bottle for my baby. It’s little pricey but worth it

We've had a great experience with the Dr. Brown's Natural Flow Anti-Colic Options bottles. our baby took to them easily. The vent system seems to make a noticeable difference, and the bottles are easy to clean and assemble. A great choice for parents looking for a reliable anti-colic bottle. Love that they are glass, I've dropped them numerous times and did not smash

Using them for 2 months now. No issue of colic as such. But, glass bottles need extra care. And it has too many parts, so need to be careful while washing.
