Sorry, I’m not a parent, but I have felt this with younger female cousins. I loved spending time with them and money on them when I was around. They were so cute and innocent and I still see them that way now even as pre teens. A man and his daughter have some special bond and to be honest, I don’t think most fathers would care that much because the love is very strong and the goal is to spoil them anyways lol. If the daughter is respectful and a good kid, why not reward them? You love them so much you just want to give them everything, although a malicious child is a different story.
