User reviews

Helpful!

It’s a reassuring resource when I know something is going on with my kid but all the other apps are glossing over it. At moments gives me my sanity back to prove yes there is something going on and what to expect. Not a must have but definitely a helpful tool if you can afford it.

4 month fussy stage

Wonder weeks app

Not accurate

Not even developed by accredited people. None of the dates ever were correct for us either

Extremely basic content

There is little value in the app for the price paid. It used to be better, but the content is very basic, the science behind it seems flimsy at worst and incomplete at best, and the community forums are filled with people simply wanting sleep advice 🫤 I wouldn’t waste money on the app. The positive is the calendar for <12month olds.

Nice idea but not realistic

I really want to love this app. But it’s just like a horoscope…the guidance each month could be read at any other moment in time and still apply. We stopped using after 6 weeks as we got no value from it.
