Babies having babies. Don’t get me wrong, some very young parents do a brilliant job, but even from when P&P were tiny, Sophie just treated them like dolls and then clearly got a bit bored of parenting as they got older. Maybe she felt like she’d missed out on having fun herself, I dunno.
What she’s failed to realise is that teens and preteens might act like they know everything and don’t need you, but it’s actually a time when they really need solid parents.
She had very limited life experience when she had them, and her quality control can’t have been up to much as their dads sound less than ideal and didn’t stick around. No doubt the cycle will continue. I’d love to know what Sophie’s upbringing was like.
