You've probably told your preschooler not to play with her food a million times over, but what if there was an activity where she didn't have to hold back? Construct little log building snacks! In this activity, you'll make logs out of celery, peanut butter and cornflakes and then have your child create her own miniature building. Not only will she get to learn a thing or two about sound structure, but she'll also have a yummy, healthy treat to look forward to afterwards. This is a great way to liven up afternoon snack time and can also work as a fun activity for your child's get-togethers.
