My 4 month old DS has recently stopped wanting to go to anyone other than my husband. He's seen my sisters and parents once, if not twice, every week since he was born so I would say he's pretty familiar with them but now he has started crying whenever they hold him or even look at him. It's quite upsetting to see and I should think upsetting for my family as they just want to cuddle and play with him. Is this a normal part of his development or is there anything I can do to help his anxiety around his aunties and grandparents?
