I was holding my baby last night and i felt a lump under his left chest behind his nipple.. it was about the size of a large grape..and seemed to move around if i pushed it... i was very nervous until i noticed he had another similar lump under his right breast, but that one wasnt as big... is this something i should be very concerned about?  I read somewhere that it might just might be from the hormones being passed from his mother when she breast feeds... (he is 5 weeks old and has only been breast fed... although recently we have been mixing some rice cereal for supported sitters in with one of the bottles we give him before bed).. please let me know what you think, his next dr visit isnt until next week... thank you.
Hi.... you are absolutely right. It could be because of maternal hormones which have been transferred through the breastmilk. You need not worry about this, you can wait till the next consultation next week and then if it is still there show it to the babies pediatrician. Regards -
