Have any of those changes affected ANY levels of the NBing pages? Have any of the NBing pages changed (or WILL they be changing) to accommodate a replacement book? If so, since I own "older" sets from LHTH through WH, are there any sets of NBing pages I should purchase now for ALL my remaining children, so that I am not forced to re-purchase resources (books and guide) to match new sets of NBing pages moving forward?
My youngest is just 3, so it will be 2031 before he moves into the last guide I already own! Should I be purchasing insurance?

Or, alternately, will you make an announcement of NBing changes enough ahead of time that those of us with more littles coming along can purchase before the old versions are gone? (So I could purchase multiple copies of just a single level that is changing in a given year, instead of 3 copies of CTC, 4 copies of RTR & Rev2Rev, and 5 copies of MTMM, WG and WH all at once!)
Thanks, Carrie & Julie!
