In all honesty, their relationship has shocked me beyond belief. Before we had Syd, Harry HATED ALL children, and he's not too fond of adults outside the immediate family. I was worried that we would have to rehome him when I found out that I was pregnant, and that best case scenario would be that he would ignore her and I'd be hyper vigilant about keeping them apart. But, no, we brought her home from the hospital and he was immediately smitten. This is HIS baby! When newborn Syd would cry, he would bring her his favorite toys and leave them with her, which was adorably thoughtful, and surprising being that he's very possessive of his toys.
Now, this little girl can do whatever she wants to do with him, and he adores it. He still hates every other child on the planet, but this one is his, and he is very protective of her.
If only he was still going to be around when she starts dating...
