Tubal ligation??

Christina • Mommy to 1 amazing 5 year old girl and 2 babies in heaven... Hoping this bean sticks!! #babydustmyway coming: July 2016
This is my second pregnany. My daughter is 6 and baby comes July via C Section. I'm 28 and considering tying my tubes. My husband agrees. My MD is ready to schedule as soon as we are. I'm nervous to sign the papers but know 2 kids is more than enough now a days. What's best?!?
