I will definitely be using LHFHG next fall with my 5yo dd (Yay

I am wondering about the recent changes to Singapore and how that will affect the lesson plans. Since Earlybird 2A/2B is no longer available, will there be an add-on schedule for the new layout now that they are in textbook form? Or is there an alternate math curriculum that would be an acceptable substitution (one that follows the sequence presented in the book)? I looked at BJU K5, Liberty K & Horizons but UGH

I noticed that several sites still offer the EB books as suggested in the LHFHG book, but I will not be able to purchase any more curriculum for a month or so and I have yet to find out how long it will be available.
Thanks in advance for any help you can offer!
