What would you do to prevent the elder sibling from feeling left out upon the arrival of newborn and mummy is doing confinement?

I got a present for #1 and gave it to her when she first met #2 in hospital. I told her it was a gift from her little brother and that her brother like her so much that he got her a gift. She was really happy to meet #2. I got her to be involved in taking care of #2 and helping me. Eg: she will help me get the diaper when I needed to change #2. She will sing to #2 when he's crying, I get her to watch #2 for a while when I go out of the room etc. She felt good when we praised her for being such a wonderful sister and she didnt feel left out at all. When I'm breastfeeding #2, she will stay beside me and read her story book, after that she offered to burp her brother.(she's just lightly pat the brother's back). She's only 2 years old when her brother was born, but she really sensible at the age.
