[EX Q]: Ben Zobrist? Kyle Schwarber? Kris Bryant? Anthony Rizzo? The Cubs donât seem worried  as they scored 822 runs last season despite Schwarberâs struggles  eventually dropping him from that spot. Assuming they donât acquire a leadoff specialist  theyâll likely rely on a combination of players seeking to provide the production Dexter Fowler supplied in 2016.
The Cubs had minus-9 defensive runs saved at that position last year. Without a strikeout-heavy rotation  defense takes on a greater role. Schwarber has slimmed down to help his agility. Ian Happ has been prone to taking curious routes to the ball.  Ben Zobrist  isnât fast  but  he âs dependable.
 Zobrist  turns 37 on May 26  and  he  played in only 128 games in 2017 because of wrist and back injuries. Manager Joe Maddon faces the delicate balance of getting  Zobrist  ready without taxing  him . Happ is lined up to receive more playing time to preserve Zobristâs health.

 Bauer  heard the radio traffic  saw a man matching the description and tried to approach and question him in or near a stairwell  according to Guglielmi. A struggle ensued and Bauer  was shot multiple times.
 Bauer  was in uniform  Guglielmi said.
The tactical officers apprehended the man  and  Bauer  was taken to the hospital  where  he  was pronounced dead shortly after 2 p.m.
Mayor Rahm Emanuel was preparing to board a flight in Los Angeles to head home Tuesday afternoon when he was told of the shooting. He arrived in Chicago around 7 p.m. and headed straight to a meeting with Johnson  the mayorâs staff said. Emanuel said in a statement that  Bauer âs death was a sad reminder of the perils of police work.
â Commander Bauer  stood for the highest ideals of our police department and our city - to serve and protect the people of Chicago â the statement said.
A statement from the Chicago Police Memorial Foundation called  his  death âsenseless.â
âThe idea that  Paul  would act so unselfishly and would sacrifice  his  own safety for the safety of the people of Chicago and  his  fellow officers comes as no surprise to those of us who knew  him  â the statement read.
Tuesday evening  firefighters at a station near  Bauer âs police district headquarters lowered their flags to half-staff. Anthony Goulet  13  came to pay his respects to the officer he said he had recently met at a community event.

[EX Q]: Sleep hygiene needs to be learned  and many companies are using the magic of technology to help parents instill healthy sleep habits in their children. The smart alarm clock  Mella   currently being funded on Kickstarter  is one such device.
 Mella  is an all-in-one sleep aid that is aiming to hit the middle ground between simplicity and functionality. According to  Little Hippo  the company that created Mella  many of the sleep trainers on the market  are either too simplistic for the price or have too many confusing buttons. Plus  many of them are clunky and kitschy  which may appeal to kids but isn't ideal for getting them to drift off to sleep.  Mella  is designed to be both simple and engaging  with a modern design and cute face that appeals to parents and kids alike.
Check out their Kickstarter video for an overview of how  Mella  works:
 Mella  "goes to sleep" when your kid does â the face closes its eyes and the night light softly illuminates in the color you choose. ( Little Hippo  recommends amber light for best sleep quality.) You can also turn on your choice of ambient sounds: rain  ocean or white noise.
Morning  though  is when the real magic happens. In addition to a soft  kid friendly alarm (that you set)   Mella 's light turns green and the face wakes up when it's time to get up.
What makes  Mella  unique is the "play period" function. Since young kids don't really have a concept of time yet  they can get antsy in the morning when they don't know how long they're supposed to stay in bed.  Mella 's play period starts a half hour before the alarm goes off.  The light  turns yellow and the face gives a little smirk ( it 's supposed to be "playful" but  it  looks more mischievous ) letting your child know that they can start to play quietly and it'll be time to get up soon.
Unlike some other sleep trainers   Mella  isn't currently app-enabled.  Little Hippo  is considering adding an app-enabled  Mella  in the future so that parents can choose which version they'd like.
 Mella  is available in pink  blue  and a limited edition Kickstarter green. The stretch goal of $40 000 will unlock a purple option as well. Pledging $39 or more will get you  a Mella  in the first batch  scheduled to be delivered in February of 2018.
