A nebulizer is a small machine that is powered by an air compressor. Though it is portable, it requires electric, tubing connects the compressor to a cup that holds the liquid medicine. Depending on the person's needs, a nebulizer can be used with either a mask or a mouthpiece.
1 One of these hormones (prolactin) acts on the milk-making tissue, building up the milk supply. 2  The other hormone (oxytocin) causes the breast to push out or release the milk already there. 3  This release of milk is known as the let-down reflex (sometimes called the milk ejection reflex). The more often your babyâs sucking causes a let-down and the more milk that is removed from your breasts, the more milk will be made. 2  Respond to your babyâs feeding cues. 3  Crying is a late sign of hunger. 4  Breastfeed your baby often.
Early in a woman's pregnancy her milk-producing glands begin to prepare for her baby's arrival, and by the sixth month of pregnancy the breasts are ready to produce milk. Immediately after the baby is born, the placenta is delivered. This causes a hormone in the woman's body (prolactin) to activate the milk-producing glands. By the third to fifth day, the woman's breasts fill with milk. Then, as the baby continues to suck each day, nursing triggers the continuing production of milk.
