How is your other child dealing with becoming an older sibling?

Penny

When our baby arrives my son will almost be 7. He's been telling me he's excited but then been telling others he's not and is worried he'll no longer be number one. How are you managing this? It breaks my heart as I know he'll be a fantastic older brother. He's sensitive, caring and his heart is so pure. I worry this could send him the other way. Any advice would be appreciated xx
