baby only sleeps on stomach

Today my baby is 2 weeks old and the only way I can get her to sleep for a long period of time is either laying on me or laying her on her stomach . I know that the doctors say not to lay them on their stomachs when they are sleep and only on their backs but my little one , if I even try to put her down on her back or not on me she only stays asleep for 2-5 mins , 10 mins top 😩 and gets fussy . My SO seems to think I've spoiled her already but I don't agree 😐 I just think sleeping like this is most comfortable to her . Is anyone else dealing with this or have dealt with it ?
