Can anyone offer advice on how to help a child, 3 �, who develops very strong emotional attachments and has trouble with transitions/changes process the loss of a friendship?

This loss triggered a major flare-up in his SPD resulting in explosive behavior. We are using a variety of strategies to help him with regulation including OT � only 3 weeks in, but already OT has greatly improved our ability to help him. He is getting calmer now, but still expressing sadness about the loss of his friend and saying how much he misses him.

I listen, acknowledge his loss and offer empathy, but I�m wondering if there is anything else I could be saying or doing to help him process his feelings.
