Telling older children....

Robyn • Mommy of two :) 26. Happily in love with my best friend ♡♥♥♡
I'm six weeks today, and my first appointment is the 27th of this month. I have two children 6 and 8. I have been dead set not to tell them until I get the okay from the doctor. But, it's getting harder and harder to keep our secret. My daughter found my prenatal vitamins and started asking questions. Also, I'm trying to remain as calm as possible throughout this pregnancy and it seems like ever since I've found out that I'm pregnant, my other two have turned into little demons!!! I feel like if I tell them, maybe just maybe they might start listening a little better, but then again I don't want to tell them just in case something happens!! I'm so torn! Hellllllp! 😰
