Does not make sense – The Wonder Weeks Review

There are glowing reviews for this app, but it does not make sense to me at all. I’ve tried switching it from due date to my daughter’s actual dob but it still has things that don’t make sense. For example. It said my daughter starts next leap in 8 days, but in another area says leap 5 does not take place until around 26 weeks/6 months. My daughter is not six months for another 4 weeks/month! How does this make sense? When I tried via her actual due date, it said she was in leap 4, but in the paragraphs below, said “_(daughter’s name)_ does not start leap 4 until..” I’m so frustrated. No one can explain to me how this app works.
