Don't worry. If you go to public hospital, you need not to pay too much. The most important thing is you need to ask your relatives to help to look after your baby if you need to go to work after the maternity leave.
I think even you have money, you may save for future urgent use or for education. Moreover, baby grows up every quickly. I don't think you should spend too much money on clothings. If the second hand clothings are clean, it is ok.
