[header] How to choose the best hula hoop (adult sized ) [title] Measure your height from the floor to your belly button. [step] This measurement will then help to determine the diameter of the hoop you should purchase. The hula hoop, when resting vertically on the ground, should reach somewhere between your waist and mid-chest. <sep> (A) [substeps] Example: if your height is 36 inches (76 "), then 118 inches (77 ") would be the minimum height. For kids, this would be 24 inches (76 "). (B) This is your base diameter measurement and can be adjusted slightly depending on your size and experience level. [substeps] For example, most adults will begin with a hula hoop between 40 and 44 inches in diameter. (C) [title] Find a hoop that you know you can balance on. [step] This will improve the stability of the hoop and prevent you from accidentally dropping the ball while on it. (D) Your waist should be about an eighth of an inch shorter than the hoop. You should also measure your waist from hips to ankles, and to knees with a ruler or measuring tape.

[header] How to start a nanny business [title] Get a list of prospective nannies. [step] Advertise in newspapers, online ads, put signs up, and give flyers. If you have experience in child care, solicit coworkers and contacts to see if they are interested in providing nanny service or if they know others who would. <sep> (A) Online groups like the sunshine and children's network are great places to begin looking. Be sure to approach your current employer, perhaps to ask if they know of a nanny who would be willing to offer you a job. (B) Also keep in mind if someone does not want a flyer they are not interested so don't bug them they might spread the word, ruining your business. [title] Do a thorough background check on each candidate. (C) [substeps] Make sure to get a roster in question. Nanny cannot become a nanny, but a general guideline for a daycare provider's operations is to have several nanny's staff.

[header] How to understand violent behavior in children [title] Consider your child's age. [step] Younger children, generally between the ages of two and four, may have a hard time expressing their thoughts and feelings because their communications skills are not fully developed. This inability to communicate may lead to violent behavior as a means to express themselves. <sep> (A) [substeps] This aggressive behavior will most likely decrease as your child grows older and learns how to express himself without resorting to violence. [title] Be aware that boys tend to be more aggressive than girls, though girls are also very capable of violent behavior. (B) Additionally, older children, as well as children up to one year old, may also have difficult expressing their emotions. For example, young children may find it difficult to communicate by writing about how they feel or binge-watching movies they can't watch. (C) [substeps] Older children, on the other hand, may still struggle with violent behaviors that they can't yet express. Their parents or those they hang out with may be frustrated with their child's childish thoughts. (D) [title] Ask what the child thinks about violence. [step] Children have a hard time understanding violence as an emotion, so they are more likely to interpret violence as another emotion.
