Thank you card etiquette

I am finally writing thank you cards from my baby shower in February. But I also got gifts after my baby was born last month. But I was too distracted and focused on healing/taking care of my baby to keep very good track or who gave me what. Is it bad etiquette to not write notes for gifts people bring you after your baby is born? I feel like I would not expect someone to write me a thank you for that. But maybe I’m wrong!

p.s. I hate thank you notes. I think they are forced and phony. But I still write them because my mom’s voice is in my ear lol
