MM L still wakes up of a night too most nights!

I feel so bad.. I was baking muffins this morning and L was playing then all of a sudden he comes running into the kitchen straight up to me while I'm getting the muffins out of the oven and burnt himself he didn't even cry or anything so I didn't think it got him but when I was changing him I noticed he burnt himself on the arm and a bit on his chest just above his singlet! Poor thing! I feel so terrible about it
