The ghost probably has many life regrets having experienced miscarriages or the loss of their kids at a young age due to illness/disease. 

Due to how you describe the ghost experiences in your families dreams its probably a key part/turning point in their life your seeing. 
They may likely have killed themselves in grief of loosing their young children.
(it was a common occurrence in olden times for women to do this when chronically depressed & emotionally unstable)
These events would probably bind them to this world until they came to terms with both in the afterlife.
. 
Most likely they were trying to re-experience what raising a child/children would of been like through your family. They probably wanted to experience the joys of seeing a young child grow up into adulthood in a good family setting that they never were able to experience in order to cope/heal their spirit.
>Poor spirit, they just wanted to enjoy/experience a mother & child's joy of life as they raised them into an adult... and they couldn't even do that in the afterlife

Where I used to live there was a famous ghost that committed suicide and was known for apparently physically pushing children away from the cliff where she died.
She was also known for slapping twinky waiters on the ass in the local bar/restaurant.
