We don't have the actual proof that Rhaegar is the father, but he is the one that took her to the Tower after he "abducted" her, and we know that she stayed there for almost a year. Rhaegar stayed there with her all the time, he left only before the Trident to face Bobby and that was near the end of the Rebellion. As for what someone said above, certainly the baby was not Dayne's or another Kingsguard's for that matter because it wouldn't have been time for that to happen, and they would have never betrayed their Prince and friend. Bran probably heard everything that Lyanna whispered to Ned so probably he will confirm everything next season.
