My poor baby

I feel so bad. I hurt Clara today. She was in the bathroom and I usually put her in front of the big mirror so she can entertain herself while I go to the bathroom. She was playing with some measuring tape and I went to pick her up and pulled the tape out of her hand. She must have been holding onto it tight because she cut herself in between her thumb and pointer finger. I feel so bad because she was bleeding and started to cry so hard. My poor baby...
