Its not Victorian at all, exactly the opposite of what Victorians tried to impose, but, as in other areas, they were fighting against nature.
Sometimes, even an experienced parent is taken by surprise at the overwhelming love you feel for a child. And this is not unlikely for a father with his first daughter. Nothing creepy about it at all!
Don't forget the closest physical resemblance overall within any biological relationship are between newborn girls and their fathers.
Not in every case, obviously, but biologically, there can be a particularly close bond there.
The theory is that an adult male hunter would not necessarily automatically see the necessity to cherish a baby girl that a) they may feel will never help them hunt, and b) for all they know, might not be in any way linked to them ( and I don't expect very early prehistoric men understood the relationship between sex and birth)
However, the continuation of the species relied particularly on adult men protecting young females, so that the next generation could be born. ( it only takes one man to continue a tribe, but many women)
And the biological resemblance and bond was an evolutionary encouragement to that. The man may well be able to see his other family members features in his new daughter.
