Do you belong to a church or a synague? Many times people are wiling to help out in these type of situations. If not then call a middle school or a local high school. A middle school student could be a mothers helper. That means you can't leave the house. I would not let her carry your daugher on the stairs or fed her unless she took a first aid class. You could get a break if she played with her and read her some books. A high school student is going to be more money but will be more experienced. Or join a local moms club and see if they can assited you in some way. Or see if there is a senior citizen apartments close by. Many seniors have lots of time on their hands maybe some sweet old lady could help you once a week for a couple of hrs.
Also I would get a big plastic container they sell them at Walmart in the storage area. Fill it with stuff for your daughter when she is having quiet time with you in your room. She will only have access to the special box when she is being quiet in your room. Coloring books, crayons, aqua doodle board, a doll, pillow pal,
I would join freecycle for your area to get some free toys to put in the box. Freecylcle is a world wide group. Its to give and receive instead of unwanted items going into a landfill.Good luck.
