[header] How to survive flight attendant training [title] Pack enough of all the essentials you will need to make it through an extended trip while maintaining a professional appearance. [substeps] Unless otherwise specified in your correspondence from the airline, bring business attire for classroom and training sessions. Bring business-casual attire for down time. <sep> (A) This includes a sweater, gloves, sensible footwear for long car rides, and a carry-on book for your reading habits. First, bring jackets, pants and boots. (B) Some airlines may provide you with a uniform during training, so you won't need to pack as many of your own clothes. Bring anything that will help you have more comfortable and restful sleep, like an eye mask, your own pillow and calming music. (C) Even a range of items such as a fishing belt and sneakers are most effective during this time period. If you know your plane has a get-together with close friends and family, bring along some casual clothes to dress up for your flight. (D) Don't pack clothes that are too formal, too casual, too old-school. The point of switching schools is to have a better idea of what you need to wear.

[header] How to make modeling clay in a slow cooker [title] Preheat the slow cooker. [step] To ready your slow cooker for cooking the clay, it's important to preheat it. Plug it in, and set the temperature to low. <sep> (A) That will allow the slow cooker to heat up slowly. [substeps] While children can help with the measuring and mixing of the ingredients, an adult should handle preparing and heating the slow cooker. (B) Cover the slow cooker and leave it somewhere out of the way where it won't be disturbed as it cooks. Doing this early will make your clay easy to mix and smooth. (C) Avoid getting hot coals inside the slow cooker. [substeps] Make sure there are no ashes or scraps of food stuck onto the bottom of the slow cooker before cooking the clay. (D) Allow the slow cooker to heat up to about 325 degrees fahrenheit (260 degrees celsius) for 1 hour. [substeps] Do not allow the temperature to go above the cool bar when you shut the electric slow cooker.

[header] How to deal with unruly children [title] Create a set of family rules. [step] Your first priority should be to create rules around the behaviors that are causing the most disruption or have potential risk for harm. If you are the main caregiver for the child, you can develop the rules on your own. <sep> (A) However, if you are the child's primary caregiver, any aspect of the rules you set should be lifted from that list. This gives you some control over any grounds that you make for your rules and will result in you creating more effective behaviors in the future. (B) Set the rules that work best for you and your family, and devise a reasonable way to enforce them. [substeps] Some rules may include behaviors related to discipline like leaving the child unattended, kicking the child out of a room, or executing a tantrum. (C) If your child spends a great deal of time with another caregiver (another parent, grandparent, or paid caregiver), then work with that person on the rules. [substeps] Make sure that the rules you develop are clear and simple. (D) If there is something the child absolutely cannot control, try to figure out what you want your child to learn and what you can change. If you adopt these rules, avoid complaining or whining about the behavior, and be sure to enforce them.
