A childless friend was visiting and my ds2 (16 months) was being his charming self. He was nattering on about the Christmas tree, the lights, the door (wanted it open), the stairgate (that open too), the cups of tea, and heaps of other words too.
After about half an hour he said "Muummmeee" and she turned to me and said "Aw, how cute! That is the first time I've heard him talk." I didn't feel I could point out to the dozy bint that he had been talking the whole time she had been there!
I must admit some of his words are not very clear, but they are all immediately understandable to his doting mum
