It's daddy's 40th birthday today and the babies were seven months old yesterday so it's a big week in the Cunnington zoo.
The babies are also practising synchronised rolling (see photo) and their parents have realised its time to baby proof the house!
They are also practising using spoons and holding their own drinks. They are trying to speak but it's just coming out as random mumbles - a bit like their parents really!
