i would look into it a little further - i don't know to be honest if the parental leave scheme can be paid AFTER your normal mat leave entitlements - i am under the impression it has to be taken at the same time....

it's nice that your OH wants to take time off, but it might not be viable if you're BF etc. it's definitely a decision to make much later, when you know how you're going to feel, how your baby is going etc. but definitely check when that parental leave is to be paid! i may be wrong, but check it out hun!
