At least in one sense. Toddlers are often asking "why?" and are very inquisitive. Genealogists need to be asking the same thing.
Why did my ancestors move from point A to point B?
Why did they wait five years to settle up the estate?
Why did Grandma say she was born in Iowa when she was actually born in Ohio?
Why did they attend the "wrong" church?
Sometimes there is no way to find out why, but often just thinking about it can move your research along.
