Last week she revealed her struggles, confessing that she is too hard on herself.
She admitted she was ‘just not coping’ and felt ‘drained’ after looking after Miller, seven months, for the day.

‘I realised that I have not been kind enough to myself and this is a HUGE problem because when I get run down, agitated or sad, I’m a lesser mum,’ she wrote.
