I found a Greek Orthodox church that's reasonably accessible - my husband wouldn't want me "uptown" with the baby at night :-). The website says the congregations stands for an hour for the Akathist. Do you think they'd make an exception for someone with a 15 lb. nursing baby?

Yes! But you might want to make sure they have pews. Even if they don't, there are always chairlike "stalls" along the sides where you can sit after a fashion. :)
