I am going to start working on LO's 1st birthday invitations and I was wondering if I was presumptious (or rude) if I wrote on the invitation, at the bottom, in small print "in lieu of presents, please donate to March of Dimes." LO was premature and I appreciate everything March of Dimes did for my LO and I feel like that's a better gift than toys (which he already has a million of). Thoughts?
