It is: more.
In Adlys world, it is: "mo!"
No matter how many times she says it, it never gets old to me and I can't let it go by without giggling, despite her ever so serious attempts to get "more" of something. The worst part is it almost always revolves around food and she's usually frustrated when asking for more so she says it aggressively and it comes off pretty rude. Adam has tried to get her to say "mo please" to take the edge off her demands, but alas, saying please isn't where her mindset is just yet. Even our babysitter that just started laughed at the end of her first day, commenting how she thought it was so funny how she yells "mo!"
Today I caught it on video as I was trying to show my dad just how much she loves hummus. In the process she yelled out an emphatic "mo!" Because well, she wanted more! (After she licked the container and discovered it was "all goooome")
