I remember meeting my second niece for the first time, when she wasn't quite a year old.
I was visiting my sister and her family, and the first morning I was there, the bedroom door swung upon like something out of a horror film and standing in the doorway was this toddler giving me a suspcious, baleful glare that would make the kid in "The Omen" look like the Black Cat's baby!Terry.
Luckily she decided that, whilst no substitute in any shape manner or form for her Daddy, I would do, if I would cuddle her when she wanted it, and feed her on a similar basis.
I should add that she's a teenager now, and a thoroughly delightful young lady, but back then... SCARY! :)
