Oh yes, some mums do get reactions to Palmer's, it seems to depend on the individual, because I know some who used it throughout their whole pregnancy without any issue, while a few others had to stop because the itching got worse after applying it rather than better. The cocoa butter formula is quite rich, so if your skin is sensitive it might not agree with you, and what worked for some is switching to something lighter like Bio Oil instead. That said, it is also worth ruling out other causes, since pregnancy itching on the tummy can sometimes be unrelated to the product itself. Either way, I would stop using it for now and see if the rash settles, and do check with your gynae or a dermatologist just to be sure, especially during pregnancy, better to get a proper opinion than to guess.
