Our first daughter was born in MA where we are legally married and we are both on her birth certificate. One as mother and one as second parent. With our newest daughter, she was born in ME where we are "roomates" so right now only the biological mom is on the birth certificate and the father space in blank. But we are in the process of a 2nd parent adoption (which have been legal here for less than a year) and then we will both be on the birth certificate!
