One night a few months ago Tyge surprised me by bringing up The Land Before Time to watch on Netflix - I LOVE that movie! We thoroughly enjoyed watching it and Tyge commented that I reminded him a little of Ducky, so that became my nickname.
Then for some reason (and he does NOT remind me at all of the slothful dinosaur) I started calling Tyge Spike. And that stuck - sorry hunny. :)
When we found out we were pregnant the first time, somehow I started referring to the little one as Petrie - like the cute, timid little dinosaur who had trouble flying.
I'm not superstitious or anything, so saw nothing wrong with calling this second little one Petrie as well. I am so thankful that this Petrie seems to be a flyer and not a faller (movie reference!), and will love him/her even if they look like a baby pterodactyl.
