Hi, my 20 month old is worrying me. He isn't talking yet (says nana for banana, and mama, and ilk (for milk) but thats it. He has only just stopped crying when strangers or indeed his grandparents speak or look at him. I work one day a week and when I come home he sees me but doesn't come up to me. He will eventually. He loves his brother very much and hugs him and he is, at times, affectionate with my husband and myself. He is now lining up his toys in lines. Am I right to be a little concerned? Your help gratefully received. x
