Hello Emma,
Yes I do get emotional at times during this TTC journey. It is only natural (I think) because we want something so bad but really don't have much control over. I don't get so much crying upset but mad upset...and then I take it out on DH

not good! Lately though I have been feeling a lot more...stable? I still really really want a

but after 9 months I realized that if I didn't calm down a bit I might just drive me and DH over the edge
As for siblings having babies....I am the oldest and only have one other sibling a brother. His wife is my age and I am in constant fear they will beat me to having first grandchild. I know so childish to worry about that but as the oldest I feel it is my place to have first grandbaby!!!! Actually last night I dreamed they called to say they were excepting and I woke up so mad...until I realized it was just a dream.
Is your sister younger or older then you?
Blessings & Babydust
