Sibling gender reveal. Have the older sibling paint a picture for the new baby to put in their nursery! Paint shades of pinks or blues! My daughter loved doing this and it was a fun way to involve her. We are going to frame it and put it in baby boys nursery from his big sister. We got so many compliments on this idea and had to share! We also let her get paint all over the white onsie which we plan on personalizing, and letting him wear for his first birthday!
