Why acknowledging the firstborn's hurt matters
A firstborn's jealousy doesn't disappear just because you suppress it. In fact, saying "You shouldn't feel that way" only makes a child lonelier.
A child whose hurt is acknowledged first gains the security of knowing they don't have to hide their feelings — and only then do they find the room to accept the new sibling. Jealousy isn't the opposite of love; it's another face of wanting to be loved.
Hori's story, where hurt grows into love
In Because I'm the Big Brother, I'll Help!, Hori feels as though Mom's arms are entirely taken over by the new baby, so he hides under the blanket and cries. That's when Dad says, "But there's something only a big brother can do."
When Hori hands a rattle to the crying baby, Hoya stops crying at once and giggles with delight. The hurt that had filled his heart melts away. Now Hori becomes a proper big brother who even sings lullabies. Feeling both Hori's hurt and his pride, a child learns that a little sibling is 'someone only I can love.'

How to soothe the firstborn's heart at home
First, put your child's hurt into words. Instead of "Don't be jealous," say "You missed being in Mom's arms, didn't you?" And create 'something only a big brother or big sister can do.' Small roles like handing the baby a rattle or singing a song give them pride.
When they help the little sibling, praise them big: "Thanks to you, your sibling smiled!" If you set aside even a few minutes a day just for the firstborn, your child confirms in their heart that your love hasn't shrunk.
The first step to growing into a loving big brother or sister
The firstborn's hurt melts away slowly with time and love. Just like Hori, your child too can grow a love for their little sibling through 'something only a big brother can do.'
