Enjoying bath time

Question. I really like to soak after a long day of work for my "me" and take bubble baths and sometimes a bath bomb included. But recently a co worker told me that a hot bath is hurting my baby! I went home and cried. Because that's all I take is hot baths. Especially during this winter weather. Did I hurt my baby? Or what about bath bombs?? Are bath bombs safe??? Help!!!!!
