How much do you know about babies and birth? Whether you’re expecting a baby, looking for baby shower game ideas, or are an experienced parent or babysitter, these baby trivia questions might stump you!

There’s so much to know about babies, and new parents often don’t know most of it until they bring their first baby home! Don’t worry, though, you don’t have to be an expert from the start — you can ask your pediatrician all the questions you want.

Besides being extremely lovable, babies are fascinating and are sure to teach you a thing or a million. Some aspects of babyhood will be such a mystery that you may not figure them out until your kid is in grade school or beyond!

Even if you’re not planning on having a baby or your babies are all grown up already, it’s hard to resist wanting to know more about a life stage that we’ve all been through.

Baby trivia quiz for parents-to-be (and baby shower guests!)

From popular names to the most common birthday to baby development milestones, some of these answers might surprise you! Check out the quiz for all sorts of strange, fascinating, and fun facts about babies.

Baby Trivia Quiz
1. What is the most common birthday?

Answer: D) September 9 is the most common birthday — in fact, 9 of the top 10 most common birthdays are in the month of September. Hint: It’s 9 months after the cozy holiday season.

2. Approximately how many bones do babies have when they’re born?

Answer: C)  Newborns have about 300 bones at birth, even though adults typically only have 206 bones. Throughout babyhood and childhood, those separate, smaller bones will continue to grow and fuse together — filling in, for example, that “soft spot” on their skull that babies are born with. That’s why calcium is so important for little ones!

3. Which of the following is NOT one of the top 10 most popular baby names for boys born in the U.S. in 2023?

Answer: A)  Sebastian was the 13th most popular boy name in 2023. The top 10 were: Liam, Noah, Oliver, James, Elijah, Mateo, Theodore, Henry, Lucas, and William.

4. Which of the following was NOT one of the top 10 most popular baby names for girls born in the U.S. in 2023?

Answer: B)  Lily was the 20th most popular girl name in 2023. The top 10 were: Olivia, Emma, Charlotte, Amelia, Sophia, Mia, Isabella, Ava, Evelyn, and Luna.

5. Babies don’t have full vision at birth. When can babies typically see color?

Answer: C)  Babies can usually see color around 4 months of age. Before that, they are gradually developing their vision. Newborns tend to only focus on high-contrast, black-and-white shapes and patterns that are close to their face, such as their caregivers’ eyes. To pique their curiosity, try placing a high-contrast baby book next to them during tummy time or on the changing mat.

6. On average, about how many babies are born per day worldwide?

Answer: A) About 134 million births occur around the world in one year, which translates to about 370,000 births per day on average, according to the UN’s estimations. But there can be a lot of fluctuation from this average depending on the season, global events, and more. Birth rates decreased during the Covid-19 pandemic, for example.

7. About how many diapers do babies go through in the first year?

Answer: C)  According to the American Academy of Pediatrics, most U.S. parents will need to use almost 3,000 diapers in the first year. Newborns can go through up to 12 diapers a day during the first month, since their digestive systems are still developing, and their tiny bellies don’t hold much. Many breastfed babies poop after every single feeding. And then there’s the pee. 

So families using disposable diapers should expect to spend at least $900 on diapers alone in the first year. This is just one of many reasons that parents often need a little extra support!

8. How many times a day do newborn babies usually need to be fed?

Answer: C)  Formula-fed newborns need to eat at least 8 times in a 24-hour period, while breastfed newborns need to eat 10-12 times in a 24-hour period. And it definitely won’t all be during daylight hours!

So whether they’re using breastmilk, formula, or both, parents often can’t manage to make any other major plans during the first few months after a baby’s birth. Of course, that intensive newborn care would seem a little less stressful if more people had access to paid family leave.
