Apple Music is available on Amazon Echo a few days early. I’ve just tried it and it works great, particularly with multiple Echo devices set up as multi-room speakers. “Alexa, play my work playlist everywhere”. Much cheaper than buying a couple of HomePods!

Infant Formula Preparation with Shortcuts

Our two-month-old daughter is formula fed. My wife and I prepare a batch of bottles every day using this formula mixing pitcher so they’re readily available at feeding time. Some arithmetic is needed to work out how much formula powder to add to a certain volume of water, and the amount of formula we need to prepare steadily increases as she grows. To give our sleep-deprived brains a break and avoid any miscalculations, I created some shortcuts to help out and do the math for us.

Formula Calculator works out how much formula we should prepare for the day, based on our daughter’s current weight (in pounds and ounces). The general rule of thumb for babies up to six months old is to offer 2.5 ounces of formula per pound of body weight in a 24 hour period. Her weight is entered when running the shortcut, along with how many feeding sessions to expect that day 1. The amount of formula to prepare, along with how much to fill each bottle with, is then displayed.

This next shortcut, Formula Prep, is the one I use the most. It calculates how much formula powder to add to a specified amount of water. Most formula powder in the US specifies one scoop (8.7g) of powder for every 2 fluid ounces of water. I specify how much water is in the pitcher and it calculates the amount formula powder to add—both in grams and scoops. I prefer to measure by weight as it’s all too easy to lose count of the scoops being added.

Prepared formula can be stored in the refrigerator for up to 24 hours. After that, it must be discarded. Formula Reminder is a shortcut I run once I’ve prepared formula that creates a reminder with an alarm set 24 hours later.

This shortcut creates a reminder so I don't forget to dispose of any leftover formula after 24 hours.

Moment 72 Hour Holiday Sale

Moment is discounting all of their lenses, cases, and accessories by 20% and offering $5 shipping worldwide for the next three days when you use the code 72HOURSALE during checkout. Moment’s lenses are a core part of my iPhone photography kit and I highly recommend them.

If you’re thinking about getting started with Moment lenses, I recommend picking up the Wide lens first. It’s a versatile lens you’ll get a lot of use from and the one I like to use the most. You’ll also need one of their photo cases for your phone—this is what the lenses attach to.

For iPhone X and Xs users1, there’s also a battery photo case with built-in shutter button. When used with Moment’s iOS camera app, the button supports half-press to focus. If you prefer to use any other camera app, it operates the same as a volume button to trigger the shutter.

Moment’s camera app has some advanced features, such as manual controls, and can also shoot in RAW. If you’re a stickler for EXIF data, you can select the Moment lens you’re using and the app embeds the information within the photo’s metadata.

  1. The case is MFi certified for iPhone X, though iPhone Xs certification is still pending. I use the battery photo case with an iPhone Xs and it works fine, and it’s expected that the case be certified in the near future.
