I gave birth to a pre matured baby on 7th January. His birth weight was 2 kgs but it dropped drastically to 1.73 kgs as he had jaundice and was not feeding as expected. Now he has gained weight but he is still 2.4 kgs and is too thin. Its been 50 days (almost 8 weeks) since he was born and exclusively breast feeding but still his weight is not increasing as expected. What could be done?
