I also think you shouldn't go for abortion. It's not fair for the baby and also your daughter...maybe she wants you to have it. Both are your flesh and blood. If you abort the baby, there's a chance that you will regret it. If talking about responsibility, you should bring the little one into this world since you've already conceived....just be careful next time.
If I were you i will definitely keep the baby.
