What should a toddler know?
They should know their parents, at least their mom. They should reconize family who lives with them. They should have a feel of the house they live in and know where which room is. They should know some of their likes and dislikes. They should know a few other basic things in life as well. Every toddler knows different things. They know more then they appear to. Those are some of the things they should know, not what they really know.
