This makes me feel icky for some reason

I'm sorry if this has been talked about before but I just got to this episode again in my 100th rewatch... Robyn making this drawing for Kody makes me feel so uncomfortable. Idk it's like she's trying to rewrite history / completely erase the bio dad or something. Every time I see this it makes my stomach turn a little more each time

I lost my father when I was 9 years old and if my mom remarried and made this weird picture AND made me call him dad immediately it would kinda fuck me up I think. I can't imagine how confusing this is for the kids? I mean her getting their bio dad to relinquish parental rights has always fucked with me but this image is the icing on the cake of just how fucked up her mind is
