My DS has recently started screaming as soon as he sees my FIL. He only has to walk in the room and as soon as he sees him we have full on tears/bottom lip and everything. He has had regular contact with all grandparents and until the last 2 weeks has been fine with FIL. Im just wondering if anyone has experienced similar? It seems to of come out of nowhere and i can tell it has upset him which then makes me feel bad.
