There are so many things in my almost 4yo's day that seem disconnected, but stem from the same basic developmental behavior. It's so interesting and earthshaking for me when I finally have that, "Aha!" moment that gives me insight into her behavior and how she's processing the world...and connects all the things that have me mystified with a common, very practical thread. These are the moments I long for as a parent, because they make sense of SO many seemingly crazy behaviors in my preschooler.
She falls apart completely, because her 2yo sister tells her she can't eat any dinner. She insists that flowers can regrow after they die if you put them in water, because her little friend said so, and cries for an hour when it doesn't happen. She looks at me in astonishment when she tells me something will happen, and I say "No". She insists she didn't do something I know very well she actually did.
Words are MAGIC to her. To Mirth, if you say something out loud, it HAS to happen, because words make it so. Sometimes, she catches nuance or joking, but the vast majority of the time, saying something makes it absolutely true...in fact, it can even reverse what's already actually happened!
It's making for interesting conversation, and also a really fun time to allow her to explore her imagination, and process and teach through fantasy. :o) More, later, maybe...our 2yo is teething and fussy..
Here's an excellent article by a friend of mine on the subject. :o)
