Research has shown that increased licking and grooming of rat pups by their mothers leads to an increased resistance to stress later in life. This maternal behavior has been associated with alterations in the gene expression of stress-responsive regions in the brain. The other options, such as more access to nursing time, nudging pups to play or providing early solid food, may have other benefits but do not specifically lead to an increased resistance to stress.
