Am I overreacting?

My husband went out with his friends a couple of nights ago and came back home a bit tipsy. He insisted on taking care of our newborn baby so I could shower. He was not drunk or slurring his words but he was being clumsy and you could tell that he had been drinking. Baby was sound asleep but I told him I was not comfortable leaving him alone with the baby as I knew he would be waking up soon. Husband got upset and said he could just rock his bassinet until I got out of the shower but I was just not comfortable with that. Am I overreacting? He said he had about 5 beers. I am also going to assume he had some shots as well but didn't want to admit it. (He's lied about his alcohol consumption in the past).
