As long as the kids are stuck indoors, why not spend the day together making a favorite family recipe? Make cooking fun with your "assistant chiefs" by assigning responsibilities. Not only will they feel important and useful, they'll also be proud of their delicious goodies. Plus, you get to sit down and enjoy the goodies together.
Some times we forget the simple things are often the most fun. This is one indoor activity that is educational and fun! Reading with your child will improve reading skills and build excitement for books. Snuggle up in a blanket with a few favorite books and read together. Take turns reading, and if your child is a toddler have "read" the book from the pictures! I think you'll be amazed at their response.
Since it looks like this weekend may be a little rainy and cool, try a few of these ideas. Have fun, and have a safe, warm, dry, weekend.
