How do you multiply ♥️ instead of dividing love between your children when a new bundle of joy is coming?

I brought elder one for my prenatal checkups, introduced her to no.2 during ultrascans. Constantly included no.2 in our conversations eg. 'Oh, next time you can read for your sibling.' 'In future, there's someone to play Lego with you' When the baby arrived, I will get the elder to help me hold the milk bottle for baby while feeding him. while changing baby diaper, I will get the elder to bring me the diaper and we kinda change the baby's diaper together. We get her involved in almost everything and now she dotes on the baby a lot. She will tell me the baby poop when she smells it, she will come running to me telling me that the baby is crying etc. She doesn't feels that our love for her is being divided, in fact she loved the younger one more.
