DD will be 2 next month. She's always been the "sit back and take in what's happening" type. She'd never be the first to run into a situation. But she just seems to be getting more and more shy. She's fine with family but with strangers almost seems to "shut down". It's not strangers in general (she's happy to run around Tesco for example and takes no notice of people if they're not trying to talk to her)
There was a specific incident yesterday that has me worried. I was at my mums and had popped to the bathroom, leaving DD playing on the floor of the living room with mum. When I came back to the room, a neighbour had called by. She's met this man several times before but she was sitting on the floor, staring at the floor, not moving at all. She didn't even react when I came into the room. I picked her up on my lap and she still wouldn't even look up. After he left she was absolutely fine.
Is this a normal stage in toddlers?
