"Tuhlader"

My 3 year old daughter has a word that uses often in place of "later." She'll say things like, "We're going to Gran-ma Shari's tuhlader" or I don't want to go to sleep now, I want to go tuhlader"

I've been wondering about that and I've come up with 2 explanations.

1. She's blending the phrase "until later." I'll have to listen for it, but I suspect we often tell her that she can't do something "until later" and, if that's true, we almost certainly clip it to "till later."

2. I think this is more likely - She's using prepositional "to" in the same sense as today, tonight, and tomorrow. All of those words usually refer to something happening in the future (like later) and it just makes sense to continue the pattern.
