I agree 100%. I'd tell her something like this:
"Look sweetie cakes, I understand where you're coming from and I want to do this thing right and make sure that I'm paying you the right amount in child support. The guy I talked to (your lawyer) said that we should get a settlement agreement in place about the time-sharing and then deal with the child support as a separate issue. Is that ok with you?"
Do whatever possible to get her to sign of on the 50/50, especially if your kid is young, because the younger your child, the less time the court generally will give a father. Look up the tender years doctrine.
In a last resort, I would agree to the $400 a month child support, then as soon as possible, probably within a year, someones income will change or child care costs will change or whatever. Any change that means a $50 change in the CS per month, or 15%, is enough to get the court to revisit CS. Then, the CS will go to what you expect it to be.
If you fight this out with an attorney, you're going to pay everything you have to spare and might not come out with 50/50. If you give her what she wants then file for a modification of child support, you'll spend less money.
Good luck.
