How to wean a toddler from bottle feeding

Image
Bottle feeding a baby is a time-consuming and stressful task. You must monitor your milk production, your baby's feeding schedule, and other factors. Once you start weaning your toddler from the bottle, it can be equally as stressful—but for very different reasons! Some mothers feel bad about denying their toddlers something they adore so much, while others worry that if a bottle isn't around at all times, their children won't get enough food or liquids. What if, then, I could prove to you that things don't have to be this way? That there are actually ways to help you through the process? Be consistent While consistency is important for all aspects of parenting, it's especially important when weaning a toddler from bottle feeding. While your child may be ready to make the transition, she might not want to let go of her beloved bottle—and that's okay! Be patient and don't give up hope if it takes your child a few days or weeks to adjust. The easiest

Advantages of Electron Microscopy over Optical Microscopy

In scanning electron microscopy (SEM), a beam of electrons scans the surface of a specimen, providing detailed, magnified images. This is different to optical microscopy , which involves viewing objects through a magnified lens using visible light. Electron microscopy has certain advantages over optical microscopy. How Do Electron Microscopes Work? Using electron beams, an electron microscope can give a very high quality of imaging, as an advanced means of sample analysis. In SEM, an electron gun fires an electron beam which is focussed through a series of lenses and apertures on the microscope. When these beams hit the sample, they interact with atoms on its surface, emitting secondary electrons, backscattered electrons, and x-rays. The microscope has built-in detectors that pick up these signals, using them to create high-resolution images and provide information on the composition of the specimen. The SEM operates under vacuum conditions, which prevents atoms or mo
