i think so, i got one of michaels many children to go woohoo with a fireman. they had one kid (feel bad for her husband and her child shes already got before meeting the fireman xD they have to have a house full of kids that arent from him just till she gets the pyro i want) but he kept refusing to woohoo at her house so they went on a tour and tried for a baby there, didnt hear the music or whatever when a sim gets pregnant but later she kept being sick and now shes pregnant.. so i dont know if she got pregnant from woohooing at the town hall place or at home some other time...
anyways how do you get pyros? my sim has had a child from a fireman but its not a pyro...is that the right way to do it XD i dont want a house full of kids who arent from her husband..just want a pyro xD
