I am going through the exact same thing. My baby is due in 9 1/2 weeks and when I offered a graduated parenting plan for Dad - working up to weekends and overnights - he said he wants "his right to 50/50!" From my research, no court in the land is going to order such a plan for an infant and I have been told most men ask for this kind of plan to avoid paying child support. Psychologists recommend that infants have a "home base" with short visits with the non-custodial parent. Also, if you are breastfeeding, that will assist you in making your point for a stable living situation until the baby is not receiving substantial nutrition from breastfeeding.
Below, please find a sampling of the websites I found supporting a stable home base for a baby. Perhaps these would help you with your ex?

Either way - for me - I will not be listing Dad on the birth certificate and am going to be taking the opportunity to relocate with my company to a new city about 7 hours away prior to the baby being botn. My situation is different in that I do know Dad, but I still will not allow 50/50 with an infant. I think with all I have been through with LO's Dad...a fresh start will be in everyone's best interest.
Hugs to you, hun. I know exactly what you are going through. Feel free to PM me...
