Yvonne: I have several thoughts on this...I'm not sure I'd call this constipation per se. It could be a maternal diet of cow-milk protein allergy manefesting as infrequent stools and green (where they stringy and foul smelling also?) Another possibility is a foremilk-hindmilk imbalance. Is the baby nursing sufficiently long enough on a side to reap the benefits of post let down milk? Green stools can be the result of excess lactose from too much foremilk. I would also query the mom to find out if she's giving anything such as iron supplements or lactose based homeopathics (this is because the lactose is derived from cow milk and in sensitive babies it will trigger allergy). There are babies who stool very infrequently when they are going through a growth spurt; although the green stools somewhat rule this out. I hope this helps.
