How gullible you beliebers really are by taking the words of OP as fact!!!!

A three year old child has no formed concept of time or numbers, this is acquired at later periods of child development, as documuented by child psychologists, during formal studies.

Furthermore, OP is home schooling so I expect if this is even true, the ideas have been given to the children and it is very easy to amke a child say what you want to hear, which has also been documented in cases of wrongly accused parents of child abuse, because social workers asked questions or gave suggestions which the children agreed with to receive rewards or words of encouragement.

Seriously folks, don't be fooled into thinking young children have awareness of space and planets, when they can barely use their visual-spatial skills to explore their own environments.
