She's said they won't be having anymore children, 100% she is just holding onto him being a "baby" a needing her, rather than letting him grow up like Vesper.I’m sure she said on the first day she dropped him off that she’d told the nursery workers to ring her if he was slightly unsettled so she’s made them contact her.
Most parents want and need their children to adjust but nope, Mick thunders in and drags him home.
