Bottle nipples go flat when there is a problem with the venting of the bottle.

If the bottle is not venting properly when the baby is sucking on the bottle the bottle nipple will go flat and won't return to normal when the baby stops sucking.

In some bottles you may have to release the cap of the bottle a little to vent the bottle and check for anything that may be blocking the nipple hole as well such as a bit of powder formula that may have not gotten mixed up properly.

To choose bottle nipples you choose the bottle nipples based on the age of the baby and how much flow they need.

Bottle nipples are sized for the age the baby they are meant for.

For example size 1 bottle nipples have a small hole which are meant for newborn babies and those that don't require a faster flow which is for ages birth to 3 months of age.

Size 2, size 3 and size 4 bottle nipples have much larger holes and are good for older babies above 3 months of age.

Special bottle nipples for premature babies are also available.

A bottle nipple is sometimes called a teat which is a flexible part of a baby bottle that allow the baby to suck on to get milk.

The teat or bottle nipple on a baby bottle contains a small hole that allows the milk and fluids to flow through slowly as the baby sucks.

The collar of the bottle goes over the nipple and screws onto the bottle to seal the nipple to the bottle.

There are different flow rates for nipples depending on the baby's age.

You can get bottle nipples that have a slow, medium, or fast flow rate.

These nipples are often numbered, 1 is the slowest flow.

Infants usually start with a smaller hole and slower flow.

You will increase the size as your baby gets better at feeding and drinks more.

A spout requires a bit more finesse than a nipple to draw out liquid.

It also supports your baby's transition from a suckling to a sucking drinking motion, which typically happens around the 6-month mark.

To support those first sips, we created a soft spout that's flexible and soft on gums.
