Is this rude to his children 😬?

I recently found out I was pregnant and me and my fiancé are excited
I’ve always wanted to be a mom and I’m so excited I started looking at and buying baby clothing and I’ve seen a lot of stuff that I’m putting in my wish list until I know the gender but I don’t want his other kids from his ex wife to feel some kind of way because I love those kids to death and would hate that
But I’ve seen some cute clothes with things like “ daddy’s girls” ,”player 3”, and shirts that say”my siblings have paws” since I’m a big animal person and have 6 pets and consider my pets my kids

Maybe I’m over thinking but I don’t want to hurt them
