No, you are certainly not alone. I was really disappointed by this too. I was hoping for child mermaids at least. Right now they can be ghosts or aliens and that's it. Vampires and mermaids (and probably werewolves too when we get them) have to hit puberty first apparently. I find this annoying for vampires soon since I often hear arguments like 'vampires are dead so they don't tan, feel the cold/heat' etc. but somehow they're still able to grow and eat regular food until they're adults? Then again, ghost children have to go to school for all eternity and I wouldn't wish that on my child/teen vamps haha... Anyway, I just hope we get toddler/child witches and fairies. That would be cute!
