I would love to help with this!
I was thinking of talking all the seasons, but then got confused on how to do seasons in Florida

Too difficult for me
So I was thinking of a new category -- how would you like one page for each month of age? If so then then I would do 6 pages total (one month, two month, to 12 months) I would have a spot for a 4x6 and a memo area with milestones to record on it.
If this doesn't work with your book, just let me know and I will be happy to take a different theme. You won't hurt my feelings! I think it's great that you are organizing this -- a first child is so special and life changing
