Can I sue my landlord for my daughter's lead poisoning?

My 2 1/2 y/o daughter has been diagnosed with lead poisoning. When her pediatrician initially caught it, it was at about 34. I was called at home and told to rush her to children's hospital so I did(and dad had to miss work to stay with our other 2 toddlers) we were eventually told that her levels had gone down and would likely continue to go down over time. We were sent home. During the following weeks the health and lead department came to our house to inspect for lead and told us they would order our landlord to replace the windows, which they believed to be the source of the lead. so to make a long story shorter, the windows were replaced yet 2 weeks later after another lead follow up with her doctor, i was again called at home and told to rush my daughter to the hospital because her levels had gone up to 52! She was hospitalized, iscurrently on meds and she's also having developmental delays(not talking ,spinning continuously, no focus).Could I win a lawsuit against my landlord?
