I'm looking for a good lotion to help prevent stretch marks. I know to a certain extent, if it's going to happen, it's going to happen regardless. HOWEVER, this is my third and I have gotten very lucky to not get any stretch marks.....yet. I would just like to take precautionary measures...just in case. I have used the Vaseline brand before, but come to find it out through education during birthing classes, it has a certain chemical which can seep through the uterus and has a chance to cause harm to the baby. To my knowledge, it did not harm the 2 I already have, but like I said, I just want to play it safe. Now the way it was presented, there are others out there that do NOT contain this chemical, and is safe to use. Any thoughts? Suggestions?
