In the positives, the baby has no colic since we started using them. That's where the positives end.

Initially, the milk flow is FRUSTRATINGLY slow and almost always stops, resulting in the baby suddenly crying, as even though they are sucking normally, no milk comes out.

There are LEAKS, full-on leaks, in the 120ml bottle, they always drip 5-10 ml, and in the 250ml bottle, maybe even 15!

Unacceptable for such an expensive bottle, especially when we have spent almost 200€ to have many and use each one once a day.

P.S. We have 8 of the 120ml, 2 of the 150ml, and another 8 of the 250ml. The problem is exactly the same in all of them, only the 2 of the 150ml don't have as many leaks.

The best bottles are Dr. Brown's. Because my son breastfed until 11 months, they were the only ones he accepted afterwards. They have endured many falls, but not a single one has broken. I recommend them without hesitation.

Excellent bottle, all from this specific company. Unfortunately, I don't have an opinion on whether they help with colic as advertised because we started using them after the first five months had already passed. They are very easy to use due to the two side notches they have, which make gripping very convenient. The plastic is also very lightweight compared to glass bottles, which is quite important considering that a 250ml feeding can last 20 minutes. This specific evaluation refers to the bottle with the narrow neck, hence the 4/5 stars. The neck is very narrow and the formula scoop doesn't fit adequately in the gap, resulting in powder being lost with each spoonful, which is not so much a loss of formula as it is the mess it creates. However, there are also bottles with a wider neck that are extremely and significantly more convenient. In the end, I ended up buying two sizes x2. One negative comment I have to make is that even if you don't fill it up to the specified limit on the bottle, sometimes it still "catches" milk on the cap, and when you take it out of the baby's mouth, the milk spills everywhere, especially on the baby's clothes.

Compared to the glass Dr Brown bottles that we have, this one is much lighter. However, the flow is noticeably slower to the point where it can be tiring if the baby drinks a lot of milk like ours does. It has never leaked milk. The small nipple confuses the baby a little, but it's okay for chamomile, which we use. The bottle is made of plastic, with its pros and cons.
