I'm a veteran of the 2u2 board but haven't been around this year because... well... I've been figuring out the whole 2 under 2 thing AND writing a book about it! When I was pregnant with Annabelle, everyone here was so great and reassuring and I've wanted to be the same but as a SAHM (I'm a freelance writer), I haven't had time to be part of this community much since Belle was a newborn.
Anyway, I just published the book so there's no free promo yet but I'll try to come back and post an update in a couple of months when Amazon will let me do a free weekend : )
In terms of the borrowing, I think you can only borrow 1 book per month. So, if Amazon's "month" hasn't re-set yet from the last one you borrowed, then you wouldn't be able to borrow another one until it does... Does that make sense? I could be totally wrong but that's how I understood borrowing with Prime.
Keep checking back though because I'm keeping it Amazon-exclusive for at least the next 3 months so it will continue to be available to "borrow" for free! : )
Re: been MIA because I've written the book!
Wow! Congratulations on the book!!!
