Valentines day for daughter, is it weird?

My daughter is 6 I'm a young mum, we live alone and I'd love to cook us up a lovely pink heart cake and maybe a little dinner and drink some soda with her on the sofa this valentines day. We love cutesy things and there's lots of them in the shops around this time of year.. the question is.. is it weird? I might buy her flowers too. I love her dearly and i know valentines day is supposed to be for your significant other but not having one and not celebrating seems a little boring.. and It's gonna be a way of celebrating love
