Human milk is the optimal source of nutrition for all infants & exclusive breast feeding is recommended for first 6 months of life. After birth newborns typically lose weight steadily  until feeding is established. Weight loss up to 7-10% of birth weight is  encountered. Pronounced weight loss is associated with hyperbilirubinemia and hypernatremic dehydration which constitute two most common causes of readmission. Monitoring a baby’s weight is therefore essential until lactation is established. 

Newborn weight loss tool (NEWT) is a potential solution for detecting newborns who are on a trajectory for excessive weight loss. This tool consist of nomogram that show hour by hour weight loss trajectories during birth hospitalisation for healthy newborns. The newborn weight loss tool is a free, publicly  available website that depicts a newborn’s weight loss  in the context of normative reference nomograms for weight loss at each hour of age. This can be used by manually entering new born data including weight. These nomograms can be used by clinicians to help guide infant feeding decisions. Participants will be visited in postnatal ward during the hospital stay and weight will be monitored daily till discharge; 48 hours in case of babies born by vaginal route and 96 hours in those who are born by LSCS. Following data will be fed as input to the NEWT tool- birth weight, date of birth in MM/DD/YYYY format, birth time in 24 hour clock format and post birth weights and timing of these measurements. Nomogram will be generated using the above inputs up to 48-96 hours.

While growth chart is an established  tool for the assessment of childhood nutrition and growth; a similar plot for the postnatal weight loss is a recent development. Most of the studies on postnatal weight loss are conducted on western population. Literature review revealed no Indian studies. Hence this study will provide insights on Indian population on the same.
