DS used to not like touching soft things such as stuffed animals or blankets/clothing. It didn't make him upset or anything, but he would be done with just one touch, and usually with just one finger before he would quickly pull away. I notice it for things like leaves, and grass and potentially prickly/tickly things. He's fine with wood chips and rocks and hard things! LOL
Any experience with this or other textures? Did your LO grow out of this? I also understand that DS is more of the cautious type, so maybe that's why.
