That's exactly what I was thinking. Or she reminded him of grandma?
It's normal for kiddos to attach to parents at drop off and not wanna leave. They also go through stages.
My favorite guy has been coming for over a year. The first couple weeks were rough, then he was begging to come. we're back to crying when mom drops off now and it's even worse when dad drops off. But he has a lot of changes happening in his life now, so he's all discombobulated.
Is anything happening or changing at home to disrupt his life? Is mom dragging out the drop offs? If so, I would try bye bye outside. Hugs and kisses and byes before they get in the door and then a quick drop off "bye, see you later" hand them off and the parent leaves
. We've been doing this for my guy minus the bye bye outside because his issue isn't that he doesn't think mom won't come back. He knows she will. He's just all out of sorts for other reasons. So she gives him a hug and kiss on the way in, no long drawn out bye bye, she hands him off, he starts to cry and I tell him "let's go see the bunny" and then he's fine
. Can you find a distraction for him? Is there anything he REALLY loves at your house? My dudes is our pet bunny. He loves the bunny and any time he's upset, she fixes him instantly lol
