My DS has recently become very shy when people he doesn't know come up and say hello to him. He often turns away and starts crying and will cling to me! He even does it with my mum who has had him to stay on several occasions. I work part time and he goes to a childminder 3 days a week.. He does go to her happily. Is this a phase that will pass? I am a bit worried about Xmas and seeing lots of extended family all together who will want to come and cuddle him!
