My little boy was toilet trained in October and hasn’t had any accidents since about a week into it. He turned 3 this week. His little sister arrived in December and in the past 10 days he’s started having accidents at home (not at nursery or if we are out). He absolutely loves his sister but I do expect it’s driven by her arrival a month ago.
My question is, how have others managed this? Do they just ‘get over it’ themselves or should we be saying something to help him with the situation? He refuses to talk about it when we ask him what’s up etc
