Oh, the wait is horrible when you are overdue, but I'm sure things will get going soon
Re the paternity leave; he can't legally be made to start his leave before the baby is born.
From Direct.gov
"How much paternity leave can you take?
As long as you meet certain conditions you can take either one or two weeks. You can't take odd days off and if you take two weeks they must be taken together.
You can choose to start the leave:
on the day the baby's born
a number of days or weeks after the baby's born
from a specific date after the first day of the week in which the baby's expected to be born
Your leave can start on any day of the week (but not before the baby is born), but has to finish within 56 days of the baby being born or, if the baby's born before the week it was due, within 56 days of the first day of that week.
If your partner has a multiple birth, you're only allowed one period of paternity leave"
Not sure what he can do about it now though, but rules are rules and his employer is breaking them by making him start his leave before the baby is even born!
