I think I've decided to take a year, but officially my ML will be about 10 months of that year, and the last two months will be using the annual leave and holidays/uni closure days I'll accrue while on ML (I get 35 days of annual leave a year, then another 12-13 days for holidays and the extra days when the uni is closed for Christmas and Easter). I'm not planning on taking any annual leave before my ML starts. It is tempting to do the whole year of ML and then add on an extra two months since that will give me a return date right when the uni summer holiday is starting, but I think a year will be enough and would rather not have three whole unpaid months.
DH gets two weeks of paternity leave (though he does have the option of sharing my leave)- his work tops up the statutory pay. He only has 5 weeks of annual leave and is taking one week at the beginning of the year, but he's also 'bought' himself an extra week for next year.
I'm still considering going back part time- either 3 or 4 days a week, but I am going to wait until I've been home with the baby for awhile to decide that!
