There are very few options available e.g. YouTube for children could be the best option but I have seen lot of channels available on youtube which are specifically for kids. e.g. @KidsKahany/videos are designed for kids to learn english through stories. Similarly you can search specific topic under youtube kids category.
Unfortunately almost all of the video sharing sites have kept themselves open with regard to content. There are some sites specific for kids that are also somewhat safe but there you won't find parenting advice or such.
I've come across one site that claims to be safe for kids and also has parenting advice videos etc.: www.kamkid.com
I browsed their videos and it seems that the videos are safe for viewing by kids but whether it would remain like that in future as well, I don't know. You should also check out www.kidstube.com. It is a kid friendly video sharing site, where all submitted videos are monitored for "kid appropriate" content before being allowed for viewing. It is a fast growing site.
The first video sharing site was shareyourworld.com.The site stopped its' operation in 2001 due to financial problems.
