Do you have any recommendations on how to treat your child when he is in 'silly' mode? Towards the evening when our son gets tired, he becomes often a bit overexcited, acts less thoughtful, and doesn't listen anymore. Any tips?

Get his attention by speaking in a stern way and showing him u mean business. U may also engaged him in other activities like singing, drawing n colouring, etc ... Bringing her downstairs for a walk around the park is great too.
