Has anyone ever used the wonder weeks app? Someone else told me about it and it's really interesting! It literally manages to tell you when and why your baby is crabby and doesn't sleep for a week!
I've had a friend rave about it but I just don't buy it! How can they really tell? Every baby will teeth//wean/develop at different times etc. It doesn't make sense to me but I think of it helps you make sense of a difficult time, why not?!
