I found this video looking for something for you n You Tube and I enjoyed it. It was made by the quintuplet's father and introduced by their older brother and sister.
The Wilkinson quintuplets, were born in 2007 and they already had a brother of seven and a sister of four, so they are now a big family of seven children. They have a blog with some videos of their life together, Rachel, their mum, writes a journal with pictures about their daily life. It's really interesting.
Did you like it? I can put some more videos or pictures if you want.
