Help please😩

I'm 30 weeks and 5 days pregnant I was so happy when I found out I was pregnant but after it hit me I soon will have to give birth I have an 22 month old toddler which I love dearly but my ? Is my unborn son dad also have a 22 month old daughter by someone else and I have one by someone else
At first he didn't want me too keep the baby he kept on saying to get an abortion but now he got attached too the baby..while I'm getting unattached to him do I need the father consent to give him up for adoption.
