Well she may not want unsolicited advice now...but she'll be looking for advice from a solicitor before she knows it.
She simply does not know Ned at all & they are about to have a child together!
There are so many potential issues ahead.. rota for visits/ where they live / money & maintenance/ schools etc.
Honestly the pregnancy is the easy bit. And God forbid the baby has any health issues or Shivvers has complications from the birth ( unlikely, as she is the best woman on planet earth)
I still find it hard to imagine her with a baby...a baby Guinness yes, but a human baby?! She is not remotely maternal & seems to be winging it re getting stuff together ( she had ample time earlier in pregnancy but didn't bother!)
