Don't feel bad. My cousin has always talked about how she wants us to be pregnant at the same time... etc. and she wants another baby and just got in this new relationiship and my mom and aunt (her mom) are all betting that she'll be 'married and pregnant' by the end of the year. And I know it sounds crazy but as soon as we tell her we're pg she will undoubtedly start trying. It sounds ridiculous to say that someone would like alter their life b/c Ben and I are having kids but my mom, DH and step-dad (the only ppl who know) all really believe that'ss true. We haven't told her yet and are waiting until I'm at least 12 weeks. She's kind of an attention hog and had her daughter a year after my older sister had her youngest and was ALWAYS competing on who 'stood first, talked first" etc. and I don't want to deal with it.
Long story short... I can understand you wanting this time to be special for your family and not something to share. Hang in there.
