If it's any help my DH is a whizz with who's entitled to what and I'm in the same boat as you. I'm a SAHW expecting this summer. I'm not entitled to any of the grants, maternity pay's or any form of help really. Of course I can apply for Child Benefit afterwards but everyone gets that despite working circumstances. DH works full time so we just don't qualify for a penny. He did read somewhere that if you have worked for X amount of hours in the past 36 months then you might be entitled to some form of SMP but I've not worked for almost 4 years now so not surprisingly I don't qualify for that either. Check the department for work and pensions website, they might offer insight on that front for you.
