XP: Trying again with XH

Tayrusso

DH and I decided to give it another try.  He's been gone for three months, and finally realized (after missing DD's first words, first steps, and first birthday) how much he loves us and wants to be apart of our family.  I'm so happy and excited, I've been praying for this for months...but, obviously, I'm being cautious, we're taking it slow, and we want to "do it right" this time.  He probably won't move back home for another month or two, but we want to avoid falling into our old routine (him not helping out and me overreacting) when that time comes. 

How do you effectively divide household chores and baby duty with your husband?
