Sadly, with a husband out of town on business this weekend, I'll be "attending" (read: watching at home) conference alone with 3 children under the age 5. So the following links are where I'm looking to keep the kids busy and somewhat quiet!
The first place to start is always Sugardoodle.net. She has links on her home page to the best resources for General Conference. I am excited about her most current packets, since you have four choices to find the one that best matches your child's interests. Be sure to visit her General Conference page for loads of ideas.
But if you don't have time to sort through her massive list, be sure to visit My Favorite Resources for a General Conference Weekend. I compiled all of my favorite ideas for April 2010 (including the General Authority tie coloring page), and the links are still good.
New this round, I'll be trying the temple lacing card from A Little Tipsy. I think that will be perfect for the nearly 3 year old Sweet Bee.
Edited to add: Saturday I discovered a few more activity and coloring pages on Prepared LDS Family. The Ant Bug loves mazes and dot-to-dots, so these links will help supplement our packet this weekend.
I hope these links and packets help your kids to stay busy and somewhat quiet. Enjoy your Conference weekend!
