Breast feeding and gaining weight

So after I had my baby november 30th. I lost 25 lbs in the first month. I was ecstatic. I've gained back 5 and feel like I'm putting on more. I eat really good! All to increase breast milk supply. I run the steps, I take care of my 3 year old, I clean a huge house daily. I'm also remodeling so I'm constantly running and lifting weight. I'm sore and very tired since I already don't get much sleep. I want to lose more weight, get healthy but idk what more I can do.

Any suggestions?
