I was putting washing out in the garden while DS was napping in his cot. I noticed he had woken up on the monitor but carried on putting it out as he was just sitting and playing with his bunny. Just as I was walking back into the living room and then upstairs to go and get him there was a massive bang on the floor and as I looked up (his room is at the top of the stairs) he was lying on the floor looking at me but not moving! Have checked him over and he's walking/moving normally and has had lunch and is talking/jabbering ok but should I get him checked out at urgent care just in case? I'm sitting here shaking like a leaf!!
