I had a thought this morning, apparently Mason needed this "time with mummy and daddy one on one". Now aside from the fact he is the only child out of their combined four that gets all day every day with both his mum and dad I would definitely argue the case that Ivy needed a break more than any of the other children.
In her short four years of life Ivy has went through parental separation, her father moving a distance away and seeing him fairly infrequently, having two older girls thrust in to her life as "siblings,", had a younger sibling born, had two great grandparents pass (according to Robbo's posts), went through a pandemic which will definitely limit her limited social interactions more and her dad now has cancer.
Yes a four year old won't understand a lot of that in the way an adult does but by Christ that poor child has suffered a lot of adverse childhood experiences.
