iPhone/iPod touch apps
I mentioned this before, but it's worth repeating. Baby Monitor ($4.99US) by CodeGoo calls you when Jr. starts to fuss. Simply launch Baby Monitor and put it in his bedroom. When he starts to cry, Baby Monitor will call a pre-determined phone number, like your home's land line. It's not a substitute for a genuine baby monitor, but certainly useful for when you forget to bring the real deal to Grandma's house.
When my son was new, we purchased a white noise machine for his bedroom. It produces five sounds, including stream, car, heartbeat, music and white noise, and cost thirty dollars.
For $0.99US, Ambiance [iTunes link] plays more than fifty sounds. You can combine sounds to create new ones and adjust settings like duration, fade out and a lot more. Updates of the app always include new sounds, and you've got the option to delete sounds you dislike to save room.
Grocery IQ ($0.99US) [iTunes link] is an application I didn't anticipate using. I'm a pen-and-paper guy (read: old geezer), and dislike typing on the phone for extended periods. It's not the iPhone's fault, the keyboard is great. I'm just quicker with a pen.
Despite this, Grocery IQ has earned a spot on my home screen. Not only is creating a list as easy as a click, you can save frequently-purchased items and even a standard list. Plus, it's a lot easier to de-select an item you've tossed into the cart than cross it off of your paper list after Jr. has tossed your pen.
I've mentioned iChalky ($0.99) [iTunes link] before, too, but both my 3-year-old and my 5-year-old love it. Poor Chalky is a physicis-aware stick figure who is subject to your kid's whims. Shake him, flip him, hang him from a push pin. It's just the ticket for avoiding a full meltdown in the middle of the post office.
