I also can't wait until mat leave - 12 weeks to go for me, all going well. I really enjoyed my first one, even though most of it was in lockdown.
The plan is to stop work at 37 weeks, ahead of the C section at around 39 weeks. My lovely boss said he'd envisage me winding down slowly and handing over from around two weeks before, so around 35 weeks. I'm very lucky with him; my previous manager was nothing like that.
@MrsTwentyNine I'd love to take 14 months but sadly can't- my plan is to go for the full 12 months though, all going well. An NCT friend had about 16 months off - she loved it. I admit I was very jealous.
