We're going to talk about now some tips. We always tell the parents when they have to use this public harness. The first tip is that they always must wear clothes under the harness. The harness might do some damage to their sensitive skin. So in the lower legs or up in the arms or in the thorax, they always have to use clothes. Now when you use clothes like these pants, some of them are really tight. They do not let the harness do all the abduction that the baby needs. We tell the parents with a pair of scissors to open where this has been made this way and that way. So the baby can use the clothes, protect their lower legs, but we won't have tension here and the harness will be able to open to abduct both hips. Other thing important here is to the hips and the thighs must form a 90 degree angle with the baby's body like here. If it is too flexed, if the flexion is a lot, first of all it's not comfortable for the baby and second we might damage the hip. We might be able to do some necrosis of the hip so we got to be careful with that. So we tell the parents if the baby grows in between the controls and the mother realized that the knees are way up, we tell them to come before to see us and we rearrange the harness. We always tell them that for the harness to work, it has to be on the baby. 24 hours a day. We only allow them to take it out when they have to wash the baby, when she has to take a bath. Then immediately you have to put it on. This has to be on all day, all night long. When it's on, the baby can rest on his back like she's here or on his belly. But we tell the parents be careful when they carry because if they carry the baby on the front, they will close the legs and this will not work. We tell them to carry over the parents' hip on the side so we maintain the abduction. Now, when you carry the baby on a car seat that they are made for them special, they won't fit here and the abduction won't be able to do it so they will close the hips. But the baby's safety is first there and the trips and cars there are not so long. So that time won't matter. First the baby's safety, then the baby's hips.
