The liquid supply system provided in the drinker or thermodrinker, see "Type" (bottles are equipped with nipples and do not use such systems).
—
Nose. An elongated spout with holes in it, usually located on the lid. To drink through such a device, the drinker must be turned over. On the other hand, spouts are extremely easy to use (the child does not need to press anything, open, etc.) and allow you to drink the contents of the container completely. Note that the spout can be made of silicone and resemble a nipple in shape, but the spout and nipple are still two different things.
—
Tube. A straw-like device: a straw (usually plastic) through which a child can draw in the drink without turning the container over. This possibility is one of the main advantages of tubes over spouts; in addition, the very process of drinking through a straw can be interesting for a child. On the other hand, no matter how deep the tube gets, it is impossible to drink the entire contents of the drinker through it — a little liquid will inevitably remain at the bottom.
—
Valve. A valve can be described as a device that opens and closes the "drinking" hole in the lid. The design of such a device can be different: for example, some lids use a “sports” valve on the spout, which is shifted up to open and down to close; in others, you need to press a button to open the
...container (and when the button is released, the opening closes automatically), etc. However, anyway, the valve is a rather complicated device for a child, so it is found mainly in models for older children (from 18 months and older). However, there are options for the smallest (from 6 months), where the valve plays a slightly different role — it limits and directs the flow of fluid, allowing the baby to drink comfortably.Age category for which the bottle/drinker is intended.
Small children grow and develop very quickly, so the age category of children's products is indicated not by years, but by months. Each age has its own characteristics of physical and mental development, and these features are taken into account by the manufacturer in the design of bottles and drinkers. It is extremely undesirable to deviate from these recommendations: a container that is not suitable for age can be uncomfortable for the baby, and even dangerous.
Now there are such age recommendations:
for newborns,
from 3 months,
from 6 months,
from 9 months,
from 12 months,
from 18 months.
