I used to be smart... I think. Two kids later and my brain is a marshmallow. I lose stuff all the time and can't remember what I'm talking about mid sentence. I am very sleep deprived.
Recently I really noticed it when I was throwing one of the kids up in the air and catching them... I did it maybe three times and realised... it. Was. The. Dog! He looked incredibly puzzled. I popped him back down and he just trotted off happily... but wtf happened there?!?
Anyone done anything equally stupid due to no sleep and to much on their mind!
