my sons dad wants to help out now financially and everything.. he has been locked up for almost 2 years. denied our son for so many months. and now he wants to be there... I still love him and want him there for little man but so skeptical... let him be there or don't let him be there... because he wasn't there for me during my pregnancy or first year of our sons life... :( and I wish he would've been... :'(
