I have to laugh and cry at the same time when I hear about parents paying for a baby sitter and all the other expenses that ad up to more than the one makes. To decide if a second income is worth it one must factor in the sitting fee, the additional wear and tear and payment, and insurance etc of a second car. Then the clothes for that job. Then the expenses like education related to that job. The list could go on and on but often when an honest evaluation of the situation many families would be better off financially if the lowest income parent stayed home or strictly only worked when the other parent was home, but that brings up other issues. More importantly being there for quality time during developmental years is priceless.
