Welcome! This is a great community and you'll make lots of friends here
I have two boys and the 2nd is definitely more difficult. I would recommend finding a local support group in your area - there's lots of resources for teen moms, whether you decide to put your new baby up for adoption to a loving family or keep him/her. Either is your decision and whatever decision you make will be the right one for your family. There are lots of kind and wonderful people in the social work system who can help you.
