I started weaning my baby at 6 months and also changed washing powder at the same time. I don't know if it's coincidental but my baby started coming up with dry skin. Mentioned it to health visitor and she said just keep an eye on it. It has progressively got worse and the doctors just keep giving me moisturizers that are not doing anything. It is on his back and his front and on his neck but it doesn't seem to bother him. Any advice or thoughts would be greatly appreciated.
