Frequently Asked Questions (FAQs) on the Best Avent Nipples

Why can’t I just use one nipple size?

It may make your baby frustrated as he may not be getting the right amount into his mouth. A way to know is to observe if your baby is sucking furiously or calmly.
If he is sucking aggressively, you need to change the nipple size.
Size matters a lot, slow flow can make your baby cranky or frustrated. Fast flows will lead to the milk spilling out of his mouth. He may even start spitting up more.

What size of nipple should I use?

Here is a summary on the general guidelines.
·    Newborn nipple which has just one hole should be used for a baby’s first month of life whether the baby is breastfed or bottle-fed.
·    Slow flow nipples are for babies who are 1 to 3 months old. This one has two holes.
·   Medium flow nipples have three holes and it is best for babies aged 3 to 6 months old.
·   Fast flow nipple is for babies who are 6 months old and older.

When should I change nipple sizes?

If your baby is comfortable while feeding, there is no need to change nipple sizes but if you notice any discomfort, crankiness, or your baby showing that he is furious, you can now change nipple size.
Go for slower nipple size if your baby is fussy and gassy. If he spits up more after meals, especially after moving up to the next nipple size, you need to get a slower nipple flow.

My child is doing fine with her feeding, but should I change nipple size due to her new age?

These age guidelines are only recommendations and we don’t think you should change nipple size just yet.
Watch your baby first and if she seems happy with a certain nipple flow, wait a while before moving to the next flow size especially if she breastfeeds.
This will prevent you from making bottle feeding so easy for her and thereby loses interest in breastfeeding.

How can I know if my baby is having problems with bigger nipple size?

The first sign you will see is milk leaking out of your baby’s mouth.
Also, notice how long her feeding time takes. If it is longer or shorter than 15 minutes, you need to reevaluate the nipple size.

What size of nipple can I use when I start adding a little cereal into the bottle?

The Avent variable flow is a good option for this as it has an extra fast flow that can accommodate liquids that are thick.
