I am 12 wks + 4 and am inclined to just get on and tell work. I could probably get away with not saying anything for a couple of weeks more but wonder if there is any reason to tell work later rather than earlier.
I'm not sure how delighted they'll be given that I've only been back from mat leave for 4 mths but there's not a lot they can do about that really!
Any views on when to tell?
