I am a mum of a 2 year old son and his father is working miles apart from us. My son knows his dad by face but they seldom talk due to working hours and some inevitable circumstances and my husband is thinking that our son is starting not to talk him anymore. This has been our ongoing issue for I for myself do everything that our son wouldn't forget everything about his dad. Is there any way or better approach that I can do to explain to my husband that he still exists?
