If you are worried about under producing milk, then wake up baby and nurse 20 min. Going back to work or school takes some prior planning. Most moms who chose to continue to breastfeed full time are able to do so if they can find the time and private place to pump their milk every 4 hours while at work. There is really no need to wean at this time and especially not abruptly. It has been reported that some babies will flip their days and sleep while mom is away and then nurse more at night.
Many moms take their babies to class and nurse quietly without anyone knowing.
Breast fed babies are usually very contented babies and welcome in the classroom and sometimes at work too, especially at this early age when they are so cute, little and quiet. If yours isn't, well, there's always the baby-sitter route. Get some aid from your local La Leche League or organized support group for methods of making it easier to breast-feed and go to work too.
