I think that I have an overactive let down. For a few weeks now (my son is a month old) my son's diapers are green, except for the mornings, when they are the normal yellowy curdy. He has gassiness periodically thoughout the day and mostly at night. We have been giving him simethicone and I think that is helping his gas. I pump in the morning in order to build up my freezer stash to go back to work and then feed him, still green. He keeps up with the flow pretty well and is gaining weight great. In every way he is doing great and is a sweet baby. Here is the question--is this something that I need to worry about? I have tried every suggestion with overactive let down that I've come across and still are getting the green diapers. Most of the days I don't worry, but occasionally I still do!
