I'm amused as to how my kids and their cousins are sending videos to each other. My niece, Zane has actually started this by telling my kids what she's eating or what she's doing in her videos. So, we sent her a response ( video) from the video she made.
I plan to create more videos for my kids' cousins because it's also a great way for them to keep in touch with each other. Maybe next time we can also record them singing songs from recorders like the new sony pcm-m10 white at musician's friend. But as of now, my daughter is excited to create a tutorial video for her cousins to see.
