I was given the timer by a friend in celebration of baby #5. I don't understand what anyone would need it for. When a baby cries, you feed it, if it smells change it and they will sleep when they're tired. I have never with any of my children had to write down what I did and when I did it, because frankly it didn't matter. Baby #4 was on a biliblanket for 2 weeks and had to be fed about every 2 hours, so that's what I did, not that hard to look at a clock and figure out about 2 hours. With multiples I could see how it could be more useful, but otherwise just not necessary. It's just one more way for companies to step in-between the mother/child relationship.
