be VERY leary of signing anything.
he's being cooperative, because YOU are.
all it will take is one goofy thing...and bam.
cooperation over.
and...frankly that could go both ways.
stardard order is not going to give him much more than 5 overnights anyhow. your little girl is only two.
throw in a couple of few hour visits and you basically HAVE a typical senirio. (not for the parents who agree to the half and half time...but with the EOW kind of deal)

SO...you could go for state mandated CS, get more CS
and still have your baby going with him the same number of nights he agreed to.

just a thought.

i know you probably dont want to rock the boat, but
someone will at some point, so either do it yourself,
or just be ready to fight fire with fire.
