My son knew the gender all along

I am 22 weeks today. Had my anatomy ultrasound Monday (21 weeks 3 days) and we found out that our second little bundle is a little girl 💜💜💜 My son knew I was pregnant before I did (he just turned 5 December 6th) and told me I was having a girl before I confirmed with him that I was even pregnant. He has been very adamant that he was having a baby sister (ring test was also accurate in both of my pregnancies). So when we came home and told him it was a baby sister, he gave me this look like, “I’ve been telling you this all along 🙄.” I’m kinda glad he was right because he definitely had my heart set on a little girl. Anyone else have an experience like this?
