Welcome rubytuesday
What you say sounds like derealization / depersonalization. It is very common in WD.

Slurred speech, word finding, it is also common in WD. It will be solved with the passage of time, meanwhile you will surely find strategies:
-When you can not find a suitable word, use another word
-Write down important things, set alarms.
(The survival instinct is powerful!)
These problems will go over time. And do not worry about the children (they are wise).
