Wrapping Presents with a 3 year old

We have a baptism this weekend and as a result we are trying to get things done for the holidays before we leave.  I was busy packing the bags for our trip while Les enlisted the girls to help wrap the presents.  I checked on them a few times to make sure they were helping rather than causing trouble.  One of the times as I started down the hallway I hear, "Ssshhhh!"  I wondered what they were up to.  So I crept down the hall.  I eased my head around the corner to see Les wrapping a present.  He was telling the girls that they couldn't tell Mom what was inside because it was a surprise.  That is when I spoke up and said, "What is a surprise?"  Emma looked at me and with conflict in her eyes she said, "We can't tell you it's a 'prize!"  I of course already knew what it was because Les wanted my imput.  So I kept asking and within 5 minutes she told me it was a camera plug.  I laughed because had I not already known this would have for sure thrown me for a loop.  I went back to packing partly victorious.  I few minutes later I heard something about not telling Mom what was in it.  I was intregued because I didn't know I had two presents.  So I returned to the livingroom.  Again I peeked around the corner and asked, "So what is in this one?"  Les not bothered by my knowing mouthed what it was to me.  I asked Emma what it was.  She again told me it was a "prize" and that she doesn't want to tell me.  Les under his breath told me to take her in the other room and bribe ber.  He wanted to see how far I would have to go before she told.  As soon as I took her in the other room she told me, "I can't tell you what it is.  It is a 'prize."  I told her I would give her some candy if she told me.  She started jumping up and down and told me what it was.

Moral of the story: Don't tell your children what is in any of the presents when they are that young.  So here is a question for you.  How old are kids before they learn to keep secrets?  I am so glad they didn't see what I got for Les.  The store wrapped if for free and then I picked the kids up from respite care.  I am so glad I decided to take the easy road on that one.
