It takes most babies seven months to realise that they are a separate entity to their mother. Let that settle in - babies take over half a year to realise they are an individual, that their feet and limbs belong to them and, even better, they are able to control them. Put a baby in front of a mirror and they will not recognise themselves.
So I guess it’s not that surprising that it takes them a further decade to realise that their parent is an individual too.
