Why? Why? Why?

I am participating in the 5 for 5 writing series at Momalom where bloggers write a post a day for five days about a given topic.  Today's topic is WORDS.

Babies make such cute little sounds when they are brand new.  I remember Liam making little grunting noises that reminded me a little baby piglet.  But then there are the times when they scream and scream and scream, when nothing you do can soothe them.  Haven't we all in desperation said to our little babies, "I just wish you could tell me what's wrong!"
Before you know it, that little baby isn't a baby anymore.  Suddenly, you have a walking, talking toddler, who amazes you everyday with the new words they are learning to say and use.  They are finally able to start putting words to their needs, making things a little easier for you when they want something.  There are still lots of moments where they are just babbling and making no sense whatsoever to anyone but themselves, but it doesn't matter.  They are finally using the words that you were so desperate to hear.
In our house, we have moved past the toddler talk phase and into the three year question phase.  Liam has words for just about everything.  Sure, there are lots of words that he still needs to learn to say, like amphibian, which he heard on a Dinosaur documentary last night, but for the most part he can articulate his wants and needs.  His biggest need is to know EVERYTHING!
The questions are constant.  "Who is that?" "What are you doing?" "Where is my car?"  And the most frequent of all questions, a single word, "WHY?"  Everything from the simplest task to the most complicated device in the house needs to be explained, repeatedly!  
I know that why is a very important word when you are three years old and learn about the world and everything in it.  But sometimes it is just plain exhausting having to explain everything.  I know that repetition is how three year olds learn and remember things but do I really have to answer the same question 10 times in a row?  And I know that it is very important for you to know the exact answer to every question that pops into your head, but I really don't know all the answers, all the time.  I wish I did.  I wish I had the words and knowledge to answer every question that my little man asks but it just doesn't work that way!  
So, even though 3 years ago, I was wishing that my little baby boy had the words to tell me what he wanted and needed, there are now times when I wish he would, just for a little while, stop using those words and give Mommy a few minutes of peace from the questions.
