So my son calls his step dad "dad" and his bio father by his name... His bio father was never in the picture he ran off when I told him I was pregnant and I filed for child support and he continued to deny him all 2years of his life. Ever since I got with my husband his bio father I guess felt threatened by him and now goes with the visitation requests. I have no problems with my son calling my husband dad because he takes care if him like a dad should his bio father wants to be dad only when it's convenient for him. Does anybody else have this problem?
