Three weeks after the baby came home, she asked at breakfast, in the same flat voice she uses to ask for more juice: “When is he going back?” Her parents laughed, because the alternative was something closer to grief. They had spent months on picture books about being a big sister. She had picked out the baby's hat. And here she was, four years old and entirely serious, asking when the experiment would end and her real life would come back.
If you have heard some version of that question, here is the uncomfortable truth: your child may not love the new baby. Not yet, maybe not for a while. The fastest way to make that harder is to insist that they do.
The analogy worth sitting with
Adele Faber and Elaine Mazlish, in Siblings Without Rivalry, offer an analogy that most parents find hard to shake. Imagine your partner comes home one day with a second spouse. “I love you so much that I wanted another one just like you,” they say. Everyone who visits fusses over the newcomer. You're asked to share your clothes. When you say you don't like this arrangement, you're told you'll learn to love them, and that you should be gentle because they're little.
It's not a perfect comparison, since a baby isn't a romantic rival. But it gets one thing right. From where your older child stands, someone has arrived who takes a share of the thing they need most, and everyone around them is calling it a gift.
What researchers saw when the baby came home
In the late 1970s, the developmental psychologists Judy Dunn and Carol Kendrick watched families in Cambridge, England, at home, before and after a second child was born. Their findings, published in Siblings: Love, Envy and Understanding, are still some of the most honest descriptions of this transition.
Many firstborns became more demanding and more contrary after the birth. Confrontations with their mothers went up, and much of the trouble clustered around the moments when the mother was busy with the baby, especially feeding. Some children went back to old habits. Others became fiercely helpful. A lot of them did both in the same afternoon.
The finding that matters most for parents came from the differences between families. Where mothers talked with the older child about the baby as a person, with wants, feelings, likes and dislikes (“He's crying because he's hungry,” “Look, he likes it when you sing”), the siblings tended to have friendlier relationships later on. Treating the baby as someone with a mind, and inviting the older child to figure out that mind, seemed to make room for a relationship instead of a rivalry.
Jealousy also isn't a flaw that more preparation would have fixed. Sybil Hart's research found signs of jealous distress in babies as young as six months when their mothers gave attention to a lifelike doll. Jealousy seems to come with attachment. To feel it, you have to love someone enough to fear losing your place with them. Later work by Brenda Volling and colleagues found that children's reactions to a new sibling vary a lot, and that most of the hard behavior eases with time. Your child isn't broken. They're adjusting.
Why “But you love your brother!” backfires
When an older child says “I don't like the baby” or “Send him back,” most loving adults rush to correct it. You don't mean that. You love him. He loves you so much.
It sounds kind, but it carries a message the child hears clearly: that feeling isn't allowed here. John Gottman's research on how parents respond to children's emotions describes this pattern as emotion-dismissing, which means waving off a hard feeling instead of acknowledging it. Children of dismissing parents don't stop having the feelings. They learn to stop showing them to you, and the feeling comes out sideways. It turns up as a too-hard hug, a “tickle” that's really a pinch, or a sudden flood of whining whenever you sit down to nurse.
There's a developmental reason this one is so hard, too. Research on mixed emotions, including Susan Harter's work, suggests that young children struggle to understand that one person can feel two opposite things about the same thing at the same time. A five-year-old may love the baby when he grabs their finger and resent him an hour later when you can't come to the park. Without help, those two feelings feel like a contradiction. Some kids decide the bad feeling must mean they're bad.
So someone needs to say the thing out loud for them, and that someone is you.
The two sentences that help
The whole move fits in two sentences. Name the wish, then hold both truths.
First, name the wish behind the jealousy. “You miss when it was just you and me.” Or: “You wish I could put him down and play with you right now.” Don't explain, defend or remind them of all the attention they still get. Just reflect the longing. Most of the time the longing isn't really about the baby. It's about you.
Second, make room for both feelings. “Sometimes you like having a brother, and sometimes you wish he'd go away. Both of those can be true. I still love you exactly the same.” That sentence does work the child can't yet do on their own. It tells them that mixed feelings are normal, that the hard half doesn't cancel the soft half, and that neither one changes your love.
Then, separately and later, borrow from Dunn and Kendrick and turn the baby into a person the older child can study. “Look, he's watching you. You're the most interesting person in this house to him.” “Why do you think he's crying? You know him pretty well.” You're making your older child the baby's expert and translator, which gives them a role nobody else in the family can take.
Feelings are welcome; hurting isn't
Allowing the feeling doesn't mean allowing everything. Some children, especially between two and five, will poke, squeeze or shove. Hold that limit calmly and firmly, and keep it apart from the feeling: “I won't let you hurt the baby. You can be as mad as you want. You can stomp, or draw a picture of how mad you are, or tell me all about it.”
That last offer is more than a distraction. A child who can draw a furious scribble labelled “BABY” and hand it to you without getting in trouble has learned something big. Even the ugliest feeling can be brought to you safely. That's the thing you want them to know at fifteen.
Your next moves
- Use the two sentences today, before there's a problem. At a calm moment, maybe in the bath or at bedtime, say, “Lots of big sisters sometimes wish the baby would go back. If you ever feel that, you can tell me. I won't be mad.” Saying it first makes it safe to bring up later.
- Narrate the baby's mind for your older child at least three times today. “He's yawning, I think he's sleepy.” “He turned his head when you talked. He knows your voice.” Then ask, “What do you think he wants?” and go along with their answer.
- Protect ten minutes of baby-free time and give it a name. Call it “Just Us Time.” Put the baby down or hand them to someone else, set a timer and let your older child choose the activity. A name makes it something they can count on, not something that depends on your mood.
- Plan for feeding time. Since much of the conflict clusters around feeds, keep a small basket of special books or quiet toys that only come out while you're feeding the baby. Better still, read aloud to your older child while you feed.
- Swap one “You love him!” for “You can feel both.” The next time your child says something unkind about the baby, catch the urge to correct it. Say instead, “Sounds like part of you is really fed up with him right now.” Then wait and see what they tell you.
A small deck for a big change
If you'd like help keeping these conversations going, that's what Bigfeels was built for. It's a deck of pick-a-feeling cards for kids ages four to nine, covering anger, fear, sadness and the big tangled feelings in between. Each card comes with short prompts you and your child use together, so “Sometimes I wish the baby would go away” has somewhere to land on the hard days, and a daily check-in turns talking about feelings into a habit instead of an emergency. You can take a look at Bigfeels here. Even if you never open it, try saying the two sentences tonight.
