The late king looked to enjoy being a father, his own upbringing did not seem very happy by all accounts.
I think much of the Queen and Princess Margaret’s rather idyllic childhood was due to their mother, who had enjoyed a very close family relationship herself, and ensured that her own daughters would have the same sort of love and affection.
I suppose if the King had lived another 10 or more years, Charles and Anne would have seen more of their own parents than they did, and their growing up would have been somewhat different. Andrew and Edward benefitted from being born when the Queen had been monarch for much longer, and was more comfortable and confident in the role.
