My baby's teat keeps collapsing. Why?

Teats can collapse for different reasons.

A block at the opening of the teat or in the air valve on the side of a teat - It is important to check these openings regularly to ensure they are clear. If there is a block, use Pigeon Liquid Cleanser or a mild detergent to carefully wash and remove any build up. Remember, the tip of the nipple is a very thin layer of silicone, so take special care to not damage.

The teat opening has become too small for the strength of your baby's suck - A vacuum is created that collapses the teat. Move your baby up to the next sized teat.

If your baby is on thick formula, the teat opening may be too small and it may collapse as the baby sucks hard to get the milk to flow - The next size teat for the baby's age is recommended if this is occurring.

If a teat has been regularly heated to very high temperatures during sterilisation - The material becomes less durable over time.

Check the temperature when sterilising the products. Please refer to the guide below.
