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.
Waste products from the baby, such as carbon dioxide, pass back along the umbilical cord to the placenta and then into your bloodstream, for your body to dispose of them. The placenta produces hormones that help your baby to grow and develop. The placenta also gives some protection against infection for your baby while it's in the womb. It protects your baby against most bacteria. However, it does not protect your baby against viruses.
