Looking for knowledgable information on turning my 2 year olds convertible car seat from rear facing to forward facing. Pediatrician says ok. Law says ok but I have read strong arguments about it being safer to keep her rear longer.  She's 13lbs under the max rear weight and ok on height. I am 6 mo pregnant so selfishly also thinking it's less strenuous on my body to get her in forward. BUT I want to do what is safest. Please no judging comments. Thanks
