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.
The number of feeding sessions can vary from day to day. We’ve been tracking our daughter’s feeds since birth and she’s currently averaging about six sessions per day. ↩
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.
Here are a few photos I’ve taken with Moment lenses:
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.
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. ↩
Darkroom for iPad beta was announced earlier today. Despite being my favorite photo editing app, I’ve long wished for it to come to the iPad so I can edit photos on the larger screen. I can’t wait to try this out.
WordPress migration complete. Micro.blog and FeedPress now working with my new feed locations. I’ve created redirects for existing subscribers so there shouldn’t be any interruption, though it’s likely some recent posts will appear again in your feed reader.
Migration to WordPress has gone pretty well, though am having some trouble with FeedPress and Micro.blog picking up changes to my feeds. I suspect it might be DNS related so I’m going to wait a few more hours before I try and debug further.
Any recommendations for selling my used Apple devices and accessories in the US? I’ve had mixed success with eBay, and Craigslist always seems sketchy. I’d normally just use Apple’s GiveBack service but I’d like to get a bit more back.
Visited my local Apple Store to try out the new iPads Pro. I’m glad I canceled my 11″ preorder and waited to see them in person now. The 12.9″ really is noticeably smaller and lighter than the previous model, and it’s the one I decided to buy.
Spoke to Apple this morning and they are sending out a second replacement Apple Watch. I know these things happen, I worked on the Genius Bar for seven years. I’m very happy with Apple’s support and responsiveness.
