I can't think of one right now. With my first, I filled out a form for enfamil and they send me 6 months long fee formula bottles. Now, I already got two smaller boxes in the mail. No clue where they're from. Probably signing up for registry or whatever
I got one from enfamil.. sent a really decent package and simalac did too although I didn't sign up for it
So far I recieved a box from enfamil ... I also signed up for similac but haven't recieved it yet
I got one from enfamil a couple days after Christmas :)
