I grew up with a mother like that. We were exceptionally well off (private education etc) in a huge detached country pile. My mum was exceptionally loving, but she was free spirited and felt she had better things to do than housework or any kind of order or organising. She mocked people with meal plans or any kind of structure or routine in their lives, preferring to do what she wanted when she wanted, floating around meeting friends, doing sports, dashing into London for the day etc. She was a great mother, cared for us deeply and was always there for us, but I HATED the chaos and disorganisation. Swimming kits/PE kits were quite of misplaced or dirty when needed. School letters that needed signing were lost if you didn't hold on to them and actually make them sign them straight away rather than them ending up on some pile of papers or another, dinners were often random (but always lovely top quality products), thing were always getting lost or forgotten. There was always money, always love, a value of education and a host of experiences, but life was too unpredictable and disorganised and at a young age I had to learn to take care of managing a lot of the life admin that most parents do for their children, because my mum was too flakey to be relied on, which made me anxious.
As a result, our house is ordered and organised, and I actually have quite a lot of anxiety around clutter, particularly around subjecting my children to a dirty cluttered home or lack of organisation. I'd have felt terrible to be the mum who forgot to wash the PE kit, or didn't sign the permission slip or was late collecting from school or sports fixtures. I still hate visiting my parents in my old childhood home which is still cluttered, dusty etc. I do have some similarities with my parents - they were great role models for being loving and kind, for valuing education, giving me great experiences and for making me believe I could be whatever I wanted to be!
It's not a lifestyle I would want to go back to, and I don't think it's a good environment for children either. That said, my children, now teenagers, who grew up in our clean, tidy organised home appear to be pretty messy and free spirited by nature - so who knows?
