Twins!! So I have a sono appointment with a special place in my area who has a 100% accuracy rate of telling the sex of the baby (in my case babies) at 13 weeks on May 22nd. My mother-in-law is pushing for a gender reveal party but I'm up in the air with it and need thoughts... and if I do the party, does that mean at the appointment we just have them put the answer in a envelope and take it to whatever we decide to go with (cake or balloons)? Is it OK for us to know and then the surprise be for the family at the party... (or does that ruin the whole idea of the party) We would have the party on saturday May 23rd (the next day) This is our first pregnancy!
