I was in a similar situation of being homeless with a small child. Call dta or go to a dta center and they will help you figure out what you can sign up for in regards to assistance. Also depending on where you are in Massachusetts there is this amazing company called healthy families. They worked with me to help me get food stamps, helped me find job opportunities, apply for masshealth and apply for the benefit that helps pay for child care. They can also help you find shelter. They meet with you once a week ( they can come to you if you cant have transport to meet them) they will bring activities to do with the little one (my person I had rebekah would bring toys and paint and coloring pages) as well as sometimes they are able to help with clothing for the child and diapers and wipes (depending on what has been donated to them)
