As noted by many, their is no right or wrong answer. However, based on the fact that your husband is earning well, and you are frazzled, do consider staying at home at least until your baby is one.

Write down the pros and cons and make your final decision. As you working is not essential monetory wise for sustaining your living, you really need to focus on other issues. E.g. Your child as a whole,you, the relationship between you and your baby, and what is more comfortable mentally.....

goodluck with your decision.....
