Pregnancy is ultimately a choice if you're lucky enough to be able to.
Save and plan for children like the majority of women have to. Thankfully, we are savers and relatively frugal as both babies were surprises for us. We still managed to save throughout pregnancy and make better choices when spending our money.
You're clearly getting SMP. As many other women will be getting or have had. I was on SMP both times as well. You can boost your income through utilising KIT/SPLIT days, accrued holiday where allowed, or go back to work early. Those are the choices many of us had to make as well.
Yes, it is shit. It could definitely be higher. But rather than playing oh woe is me, I suggest you check your privilege and appreciate the fact you're having a baby when many can't, you have a profession and job to return to, you are entitled to a nominal income through your work place and smp, and that you have a partner who can help support your family.
It's not discrimination that the government has put in place a minimum guaranteed income to help fund your mat leave and that your job will remain safe for a year. It's due to discrimination that these things have been put in place.
You are coming across as an entitled spoilt brat. Big deal, you're a teacher who's pregnant, will have a baby, and get SMP. You are not unique. No one is forcing you to have a baby you can't afford.
The country is at breaking point and isn't able to provide enough support to services like the NHS, public services including schools, the police, fire fighters and other essential services not to mention just a better basic standard of welfare and you want special treatment and an enhanced maternity leave package? Please show me where this magic money tree is.
You should be counting your lucky stars that you have it so well over here. There are many much, much, much worse off, and this type of entitlement is sickening.
