Two and Done Vs Three and Done

I hear all over the Internet mostly on parenting boards people debating this situation. For me at the moment I am two and done or at least I try to be. Coming from a family of 3 children I do sometimes feel like I am missing someone in my own family. There is also all the comments it's is kind of like a cycle. stage 1 : new baby is here and they ask if/when are you having another child? stage 2: ( can branch off in 2 ways) way 1- If you have the opposite sex of your child you get the whole are you done having kids? way 2-you have the same sex and you get are you going to try for a boy/girl? stage 3: you have that 3rd and people assume it was a accident a slip up. Any child after that I suppose they think your crazy! Well here is my scenario I have a son and a daughter so I guess I should be done as my aunt said " you have a boy and a girl, theres no reason to have another" so I said I could have an alien. I struggle with the two and done dilemma constantly because honestly I feel like I am missing a child. to be honest here I think the reason I decided for now I am two and done is our families have so much negativity about another child. yea yea I shouldn't listen to them its my life.........but I do listen. so Yes I am two and Done but I WILL NOT do anything permanent to keep it that way.
