I went straight from size 0+ to 6+ months.
The baby is now 3.5 months old.

I believe it's not worth going for the intermediate 3+ because the holes from the company are generally very small.

As soon as I changed it, the whining stopped.
Like new now.

I was not satisfied.. it is so soft and as the baby drinks it goes inside it is not worth it... with fricolac comfort no bad milk comes out at all.. nuk only!!!

It doesn't lose milk, sometimes maybe 1-2 drops come out, but I think it also has to do with how the baby sucks at that moment. As for sizes, the milk also plays a big role. We give frisolac comfort, due to its density and somewhat thick consistency, we switched to size three from the second month.

Very good and of high quality, it was received immediately. Generally, everything we have bought from Dr. Brown's is excellent. Just be careful, if the milk is too hot, it loses its milkiness, but that is understandable

All good!! In communication with our pediatrician, he told us that we will change them somewhere around the 6th month. Uh, at 5.5, I noticed fussiness with the food, so I changed them. Excellent quality, our bottles became like new

From No1 to No2, do not delay it too much, especially if you notice complaints during feeding! We changed it at 2.5 months and we were very late!!

Dr Bronw's is only for children! It solved our hands. It is also suitable for younger babies if you give them milk for colic because it is thicker!

Good enough, but my little one struggles with the fast FLOW, I might need to buy the regular FLOW

Very good flow, we used it a little before the 3rd month, the baby got used to it very quickly and started drinking more easily!

Very good company. The fact that it produces all nipple sizes helps to keep the already very good bottle for a long time of use. The first few times the nipple is changed to a larger one, it requires a little adjustment. Because more milk comes out. But once you get used to it, it's convenient. Because the meal becomes faster since the ml has increased. And it doesn't get tired of pulling from the smaller nipple.

What you need if your child eats greedily or has colic.
Obviously it only fits the corresponding bottles.
