I’m working from home so probably won’t tell work until the last week before Christmas or will wait until after and tell them in January.
Sort of hilarious that I need to renew my professional development plan for a meeting next week. Where do I see myself in a years time 
In all seriousness though I think I’ll be back in work for September 2021. I’m not far enough into my career to take a year off and it not really impact progression. I’m also the main earner so DH will take a few months at home with baby once I go back.
Also don’t want my work to absolutely crap themselves if I get pregnant with a second in a few years time.
