Modular design allows for ease of adding optional. features to the master controller. Connectors are pro-. vided on the electronic printed circuit board to accept. the heat/fan, setback/warm-up and/or flow control. modules. Modules are color-coded for visual aid in. selecting the desired temperature control sequence.
Gas pains are due in part to an immature digestive system. As the baby processes the nutrients from breastmilk or formula, gas bubbles may form and get trapped in the stomach or intestines. Air bubbles can also be caused by swallowing air while nursing or drinking from a bottle, or even from excessive crying.
There are two main causes of gas: swallowed air and the normal breakdown of undigested food -- especially sugar, starches, and fiber. Your body expels this gas through burps and farts. Everyone does it. In fact, when your body is healthy, it's normal to pass gas 14 to 23 times a day.
