I think it's okay to have your child on youtube, but I would use caution. Even though your child is small now, one day she might apply to college or for job. Colleges and recruiters are now examining your child's social networking profile, so it's good to have one, but just makes sure it represents the best your child has to offer. Your video is cute and won't harm her reputation. When she's older, it's a good idea to review what's appropriate to post with your child. If your child has a friend in her video, you should get her parents approval before posting, even if it's shared with family and friends only. For me, this goes for Instagram, Facebook, Twitter and so many other apps your child will eventually want to upload to.
