Family members of parents-to-be Prince William and his wife Kate are confident that the couple will carry out their parental duties very well.
"First and foremost, everyone is ecstatic for both," eonline.com quoted Prince William's cousin Peter Phillips as saying in an interview.
Phillips said the newborn will be a playmate for his own daughters.
"They will make great parents and it's great to be able to welcome another child into the family, if not from a selfish perspective for my two girls to be able to grow up with a playmate," Phillips added.
