I was a latercomer to this party (thanks, Shannon!). Here is my list, if it's not too late.
Here, here on the books! Classics, nursery rhymes, rhyming books, baby signing
Classical lulluby cds
Clothing (6 months and up) from http://www.sagecreeknaturals.com/
I have a registry at http://www.extraordinarybabyshoppe.com/
. I requested modifications today - see when it was last updated to confirm it's up-to-date.
Of course, handmade items are also appreciated. My little guy also has enough blankets to keep warm his entire babyhood...
Happy showering! I may even get out today to purchase my mama's gifts!
