I always knew when my dad's wife's kids had kids mine would pushed to the back burner because her kids always come first. It finally happened and now my almost three year old cries to talk to and see his mimi, G, and aunt brailyn( my baby sister she is 9 years old) but they dont call him anymore or come visit and wont answer my phone calls. But thats fine he is young enough to forget them and it will be their lose not his. I told my husband the have one last chance with me and that is this sunday on my son's birthday he will turn three and 'f they cant even pick up the phone and call him they will never see my children again. I will not allow them to hurt my babies.
