Do Tongue Ties Really Cause Breastfeeding Problems?

In recent years, surging numbers of infants have gotten minor surgeries for “tongue tie,” to help with breastfeeding or prevent potential health issues. But research suggests many of those procedures could be unnecessary. It’s uttered in hushed tones during mommy-and-me yoga classes and at Montessori-school drop-offs, discussed ad nauseam in breastfeeding support groups and on parenting message boards. It’s called tongue tie, and it’s everywhere. In online mom groups, it’s blamed for all sorts of parenting woes. Baby isn’t gaining weight, or won’t take a bottle? Have you tried checking for ties? Kid won’t nap? It’s probably related to tongue tie. Baby have a rash? Check under the tongue! Tongue tie, or ankyloglossia, is characterized by an overly tight lingual frenulum, the cord of tissue that anchors the tongue to the bottom of the mouth. It occurs in 4 to 11 percent of newborns. A lip tie—a related condition—is an unusually tight labial frenulum, the piece of tissue that keeps the upper lip tethered close to the gum line. Tongue and lip ties often occur in tandem. To breastfeed effectively, babies need to create negative pressure (in a word, a vacuum) on the breast. This diffe...

Generally speaking, the steel flanges refer to the joints specially used for connecting pipes. For example, two steel pipes with a diameter of 100 can be connected by welding or electric welding. Once welded, it is not easy to disassemble unless it is cut by a cutter or Electric welding to cut open. However, if a flange (usually a round flange) is used, a gasket seal can be added and then fixed with a screw cap. It can also be easily disassembled when the pipeline fails or is overhauled. In addition, if there are flanges on both sides of the large gate valve switch, it is convenient to remove the switch. The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt w...
