Only 3 questions :) thanks!

These question needs a one word answer :)

I LOVE Christmas! I was just wondering what you want for Christmas?

When I was a newborn all the way up to now when I have 2 daughters we had amazing Christmases. I just wanted to know some of your Christmas stories.

I have a funny one from when I was about may maybe 9?

My brother woke up at 4 am! He came in and woke me up too (when I was just fine sleeping) and I couldn't go back to sleep becasue I was to excited. We walked into the living room and we snooped through gifts. My brother was so anxious to see what he got he tear open every single present he got (just a little) and saw what they were. Then he would quickly tape the bottom shut, to make it look new (it looked far from the way they did before) My parents had a fit, but luckily let him keep hi gifts. I can't believe I can still remember that story :)

What are some of your Christmas stories?

My youngest daughter is 1 month old yesterday and I had her sleep in my room. We moved now and we have an extra room for both my toddler and my newborn. I was just wondering if any of you had ideas about where I can buy some storage containers or baskets or anything to organize things in a nursery. Anything helps :D Thanks!

My two daughters do absolutely hilarious things sometimes. My daughter was looking at the mirror (she is about one) and she was babaling and looking at her feet. When she looked up at the mirror she was startled and made a hilarious face. I felt bad that she was scared but that was a moment I wish i caught on camera. Tell me some of your funniest baby moments :)

I am "due" this month, so when I signed up for free emfamil formula I picked the bullet that said *I am due this month in December. I was just wondering when i should e expecting the formula. Thanks :)
