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 primary sources of intestinal gas: gas that is ingested (mostly swallowed air) and gas produced by bacteria that normally reside in the colon (a process called fermentation). Bloating is the full feeling individual gets due to the retention of gas in the abdomen.
