She's 93 and my appointment is an hour away or I would take her with us. I think we are going to do balloons or something similar. We did the cake thing with my first and want something different this time.
You can take her with you to the u/s
You can buy a cake with the color inside it nd have her cut it to let everyone know the gender.
You can wrap a box and put the color of balloons inside and have them open it
