Surname ni baby

Di pa po kami kasal ng father ng baby ko, pero sure po na surname nya gagamitin paglabas ng baby namin, balak po namin magpakasal maybe 4 years from now pag nakaipon na at magkakasama na kami ulit, at balak ko po na maghyphenated surname since gusto ko pa rin ikeep yung maiden surname ko at gamitin yung surname nya. With that plan po, pwede rin bang magtake yung anak namin ng hyphenated surname? Or hindi po? TIA ?
