what u say is correct in real life.but in this show they will show veer is brainless but rathore is intelligent.let iccha and veer cell start working and child can reunite.even today mai told that iccha forget about her own kid and took care of khana and muktha. it is true if veer is there in labour ward this swapping will not happened.rathore will not do like this.he will make others to understand .veer knows to shake his head for iccha
