Not necessary – The Wonder Weeks Review

The only thing I like about this app is that it estimates where your baby might be more fussy than normal. However, it’s not always accurate and there’s no guarantee that it will be. Then throw in other factors like teething and you still don’t know what the heck is going on until you see a tooth (or not). The price isn’t outrageous so if you have a couple bucks that you feel like burning, then go for it. But I kinda wish I hadn’t bought it. I’m sure there’s several online resources to tell a parent the gist.
