4 oz/120ml Narrow Glass

Good glass quality and price

Good design

Excellent

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.

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.

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

I thoroughly enjoy these bottles! They are safe to use and clean well!I was concerned about glass and the bottles potentially breaking but I have accidentally dropped twice and there have been no cracks.The fat from breast milk doesn’t stick to the side as easily as plastic bottles. The bottles also clean easier, the milk just slides right off the sides!I was also concerned with the ease of holding but have had no issue. They are obviously heavier than plastic but it’s a small bottle to begin with and I don’t even think of the weight.The size is great since most breastfed babies drink 3-4oz on average!These bottles come with a level 1 nipple flow but can be replaced with any level flow. Dr. Brown sells just the nipples.I’ve had no leakage issues.I also love the longevity of the bottles - with them being glass they won’t need to be replaced like plastic bottles!! It’s worth the money!Also I feel confident using these bottles for my baby since the glass is free from microplastics!I know these bottles have more parts to clean than other bottles but it’s all we’ve used so I don’t even notice. It may be difficult to switch to these if you’ve used another kind.
