Re: No Boxed Gifts for a 1st Birthday?!
What a fantastic and very sweet idea! I wouldn’t word it as no boxed gifts though- perhaps something along the lines of “We are raising little readers and we would love it if you would share your favourite storybook with our twins!” And then ask your mom and sister and mil etc. to mention by word of mouth, if asked, that this is in lieu of any other kind of gift.
