DS is 3 in a few months
He has a complete meltdown when his nan has to leave or we have to leave her house. Screaming, kicking, climbing at windows, banging at the door, crying, sobbing. Literally uncontrollable - I cannot soothe him.
The kicking and screaming calms within say 5 - 10 mins but the sobbing, crying and then general unhappiness lasts for sometimes a few hours. He'll basically be a stroppy teenager for a few hours after.
I've explained nanny has to go to her house and we'll see her X day (she looks after ds 2 afternoons a week so it's regular contact) but I don't think he understands. He's slightly speech delayed and seeing speech and language, paediatricians etc. Though his understanding is usually really good so he might understand but just not be pleased about it.
She just says she has to go, gives him a kiss and cuddle and says bye and walks out. He starts this as soon as she says she has to go now.
Any ideas what I can do? It's awful seeing him so upset and not being able to calm him.
