The Science Behind What a Baby’s Bib Catches: More Than Just Spit-Up!


Babies are messy eaters, there’s no doubt about it. That’s why parents always make sure to use a bib on their little ones during mealtimes. But do you know exactly what a bib is catching? It’s more than just spit-up, and in this article, we’ll delve into the science behind it.

What a bib catches

Firstly, let’s talk about the obvious – spit-up or regurgitation. This occurs when babies bring up milk or formula from their stomachs. Next, there’s drool or dribble which is very common in younger babies whose salivary glands are still developing. Lastly, older babies and toddlers can make quite a mess when they’re learning to eat solid foods, so a bib is essential for catching those food spills and messes.

The science behind a bib

To understand the importance of using a bib, we need to look at the anatomy of a baby’s mouth and the digestive system. Babies have small mouths and their tongues take up a lot of space, making it difficult to effectively swallow and control the flow of liquids. Additionally, their digestive systems are still developing which means they can’t handle large amounts of food at once. With all that in mind, it’s clear why catching excess liquid and food particles is crucial for preventing choking and aspiration.

Choosing the right bib

Now that we know the science behind a bib, how do we choose the right one for our baby? Firstly, the material is important. It needs to be soft and absorbent for maximum effectiveness. Secondly, it needs to be the right size for your baby’s age and size. Lastly, the design and style of the bib is up to personal preference, but some parents love the convenience of snap-on bibs or those with pockets that catch crumbs.


Using a bib on your baby is more than just preventing stains and messes. It’s actually a crucial safety measure that can prevent choking and aspiration. Not to mention, it makes clean up a whole lot easier! So next time you think about skipping the bib, remember the science behind it.
