I started using iBabylog when my baby daughter wad just a few days old. Her father had been logging info on sheets of paper to keep track of feeds, diapers and sleep.
The app made it so much neater and easier and I love looking at statistics. Stats helped me visualize my babys cycles and it helped set up a routine. It also showed me that I tended to let my baby feed on one side longer than the other and I was able to adjust.
A great logging and organizing tool!
