Okay well, here they are - my first attempt at Infant Mat making.
My friend Dannie made something similar for me when I had my baby (11 months ago). It was my most useful tool - I took it with me from room to room and laid him down with me wherever we went. Later, when "tummy time" became important we used it for that - and in my house (where every room is hardwood flooring) it turned out to be essential. These Mats are super thick and comfy.
