My sister-in-law had her GB removed after her 2nd child (she has 3).
This is why I decided to pre-empt any problems...I have an 11-month-old son and plan on another little one about 2 years from now.
I am 33 years old right now and just about everyone in my family over the age of 40 has had their GB's removed except my mother who decided to flush and keep hers!
