I'll call it a piddle pad!
Dd2 is out of nappies now (just) and is fairly reliable. Tomorrow we need to go grocery shopping, so it's her first outing in knickers! I needed something to go under her 'just in case'.
So I remember I had some water proof sheets, but they are HUGE. So I cut them down, cut up some old towels & put them together. The towel, I figure will hold more liquid than just the waterproof stuff (they are covered in thin fabric, but not enough to catch much).
I am planning on sitting her on them in the car seat/trolley etc. It isn't far, but I won't have access to a toilet. Although she does seem to have great bladder control
Very proud of my first creation. Albeit very rough, it will do the job!
