I will extol the Lord at all times,
his praise will always be on my lips,
My soul will boast in the Lord;
let the afflicted hear and rejoice,
Glorify the Lord with me;
let us exalt His name together.

Developmental psychologists look at moms and try to figure out what kind of mom is the best kind of mom. One study looked at children in kindergarten who seemed to have it together. They interviewed all the moms and then matched them to the children. They dubbed the mom's of the children who had good self esteem the '30 second moms.' These moms did their own thing, but if the child needed them, they stopped everything and concentrated completely on the child. When the problem was solved, these moms went back to what they were doing. The moms of the children who seemed to lack good self esteem were the 'hover' moms and the neglectful moms. Moms who hover over their children all the time or those moms who were there phsically, but who were not there psychologically for their children, had children who were clingy and unable to do for themselves.
I know you missionary moms have tons to do, but take out those 30 seconds throughout the day to be there totally for your children. It will pay rich dividends.
