Help I don't know what to do

So I found out that I was pregnant last week. I have been with my boyfriend for almost 3months. I already have a 2yr old lil girl. Anyway I suggested to my mom about adoption because my boyfriend doesn't help me with anything he just sits around and does nothing. I am barely able to support my daughter our dog and myself. My daughters' dad has been helping me with a lot lately. I want to keep the baby but I also want to give it to someone who will be able to take care of him/her. What do you ladies think I should do??
