If you’re a new family hoping to add another member someday—or soon!—then you might sometimes worry about how this will affect your firstborn. How will she feel when she’s no longer the center of your universe?

Popular wisdom holds that introducing a new sibling is inevitably difficult and potentially even traumatic for the firstborn child. But the truth is that expanding your family can be a joyful experience right from the beginning if you help your little one create a strong relationship with her baby brother or sister—even before the baby is born.

Our mission at the Reading Womb is to educate parents about the importance of bonding with babies by starting a regular storytime even before birth. And prenatal bonding, especially through reading aloud, is also the very best way to build strong sibling relationships!

By the time your second child comes along, you’ve probably established a regular read-aloud routine. We hope you even read to your first child in utero, and she’s a book lover already! Whether storytime is part of your family’s schedule or not, reading to your firstborn and expected child at the same time is way to continue or ingrain a practice that is integral to successful families.

Think about it: you’re sharing with two little ones at once all the joys of language, literacy, and bonding through books, and at the same getting some relaxation time for yourself. Now, that’s multitasking at its best!

Research has shown that babies can hear and remember voices from inside the womb during the last trimester—so let your first child know that the baby in Mummy’s belly can really hear her talking. The sibling-bonding magic happens when your child actively joins in the read-aloud with you. She can repeat some of the lines from the story after you read them, or even read some words herself if she’s old enough. Meanwhile, you can help her describe the pictures to the baby and add her own details to the story.

We can’t resist sharing a glimpse of the “second sibling” in the Belly Books collection! Hey, Little Baby was created specially for little ones to welcome a new baby brother or sister into their world. By telling the baby-to-be about all the fun they’ll have together, your firstborn will develop a sense of excitement about the upcoming birth—and a feeling of companionship that will ease the adjustment.

There are so many benefits to both grownups and children from family storytime, even just 15 minutes a day. Setting aside this sacred time to share the joys of language and story is a beautiful way to just be together as a family. And if you establish daily reading time with your first child, then when the new baby finally arrives, this will continue as an expected and comforting routine as you all settle into life as an expanded family.

Goodbye, sibling rivalry—hello, sibling revelry!
