DH gets 12 weeks unpaid paternity leave but he can use 40 hours of sick leave and then is able to use up his vacation leave for any remaining time off.
With DS, DH took 3.5 weeks off so I could recover and he could help with the steep learning curve with a first baby and nursing. He had plenty of sick/vacation time so this was at full pay.
Luckily, DH is a teacher and has summers off so this time around he will be home (with no pay as he is not on contract but that is our normal summer) for about 6 weeks before he goes back to work to prep the classroom. I'm thinking that will really help DS transition and not feel left out.
