So many of us have wood floors now throughout our house. For me there are WAY more pros and than cons. But an obstacle I came across when Brant, now 4, was 8 months old was he would try to hang onto a toy to help himself up and the toy would slide. Of course he would fall or get frustrated. I bought a "Thick Grip Shelf Liner" from Target for my cabinets and had some to spare. I started putting it under these toys and it helped keep them more stable.
