We live away from family and not very close to friends so he's only really seen adults from a distance, especially during covid. He is fine with other children but if adults approach him he outs his head down, sometimes covers his eyes and his bottom lip comes out. He won't look up until I assure him they've gone and then when he knows they've gone he gets upset like a relief and won't let me go.
He doesnt go to nursery and won't until January when he turns 3.
Amy advice on how to deal with this?
