Even a brief period of maternal deprivation could have long term consequences on the child
Early life brief material deprivation modifies adult brain function and cognition - short science articles

Researchers have found that when a baby is taken away from its mothers even if for a brief period of time, this event alters the future development significantly. This was observed in a rat study in which the pups were taken away from their mother at 9 days of age for just 24 hours. The changes in the brain of these pups in their adulthood were similar to the brain structural differences seen in people at risk of neuropsychiatric disorders like schizophrenia. There were signs of memory impairment as well as decreased communication between different brain regions. This could increase the risk of mental illness and addiction later in life.
