Advent has made a specialty of anti leak cups to my delight (I exaggerate a little it's true). Before going further, not starting the beginning:
Presentation:
I have the black model. The mixture of black and blue is the most beautiful effect and it changes too classic blue and pink. A little penguin is drawn on the cup. The mouthpiece is made of a flexible material
The handles are convenient and allow the baby to hold the cup well. Anyway, on that side nothing exceptional. We are in the required minimum.
In short, the design is nice and dimensions make it easy to handle a baby by cup.
Use:
The assembly and disassembly is very simple to achieve. Sealing is provided by a small plastic circle (is silicone, plastic, I did not find info)
The water flows when the baby exerts suction on the spout. This is a little closer to what he does with a bottle. However, it will require a small learning from him.
All parts go in the dishwasher and can be sterilized
The strong point of this product is its compatibility with nipples "natural" Advent. Therefore we can replace the spout by a teat. This avoids the need to buy a small bottle of water and then a sippy cup. It's rare enough from one manufacturer to be stressed. Obviously, this therefore requires you to buy Avent bottles and teats. The range "natural" is not really given.
In conclusion, I recommend that cup
