Still not crawling

They still do not start crawling :) Maybe we hardly put them down on the floor, instead they were in their walker all the time. Hubby just made me realize how unsafe it is to put them down in our hall as the floor tiling was not done properly. There are many sharp corners between the joints which may cut their delicate skin if the crawl on their tummy. But we still need to put them down, don't we? Sigh....if only we can afford to do timber flooring on our whole floor for the kids!
