I think this can be true for some people (equally it can force maturity too early) but Jack was 23(?) when she became a mum. Certainly young, but she should’ve outgrown a lot of her teenage-like behaviour by then. I had my daughter at 24 and on reflection I was pretty immature before that - but nothing like JackI’ve heard the same said of young mum’s, and it was certainly true of my mum. At times great fun to have a mum constantly 17 years old, at other times... well... let’s just say jack reminds me of someone at times...
Can’t help thinking maybe that she’s stuck at the age she became a young mum too.
(No disrespect to young mum’s btw. Like I said, my mum was one and she did a great job. But she was always very young at heart in both the positive and negative ways at times)
I think she’s just a twit, which isn’t generally something people grow out of
