To delay maternity leave?

[Bringonthesn0w]

I’m a teacher and due in August, which I always have off for obvious reasons. I feel a bit cheated that I would have to take maternity leave at the end of term and therefore the pay I would usually receive in August will be substituted with SMP. It also takes a month leave from me. My mum had a suggestion to set my maternity leave as the day the baby is born to get the full weeks paid without cutting into my holiday or maternity. I’d ideally like the full year off which would take me up until the summer holidays again, possibly only return for a week before summer holidays begin.
Now I know this may seem cheeky but AIBU to do it this way and would my workplace accept this?
(presuming I’m in good health and can work to the end of term which will be 18th July)

Just to respond to some queries

Shared parental leave works even if your partner chooses not to take theirs. I did mine this way, baby was due September but arrived in August, had mat pay until December when it reduced to statutory pay, I then applied for 3 blocks of pay.

I technically went back to work for the two weeks holiday during Christmas. SPL until Easter holidays where I went back to work again for 2 weeks, then did a further week during the May half-term. Was 5 weeks better off pay wise. This obviously depends on the shared parental leave pay and your maternity rights from your school but your school legally can't reject it.
