She doesn’t like kids & never wanted to be a Mum as we know and it shows. She’s wildly naïve about motherhood and is jaded by her own weird take on it. She clearly has some deep seated issues (being sent to boarding school?) about a mother’s identity and role. IMO She was ok when he was small and she breastfed because she had a job description, she looked around and copied what she saw but then it got too much, she had to improvise, take initiative, adapt to his developing personality and she was lost. She doesn’t like to not be the best at something so ran from him. She can keep a baby alive but beyond that she doesn’t know how to engage and respond as a parent. She’s takes on weird adult ideas like ‘be kind, share, don’t be spoilt’ that he can’t comprehend because she doesn’t understand children. It’s very sad to see.
