Denied exemption from jury duty - baby is not even a month old

I just had my son at the end of January and of course received a summons for jury duty. I exclusively breastfeed every 2-3 hours and my husband is back at work so I obviously would not be able to be in the jury. I submitted a request to be excused and was flat out denied. I am so pissed. How do they expect me to attend jury duty not even a month after my baby is born? And yes, I am in the US.
