Custody is ugly 99% of the time. You need a mediator. If he makes more than you, you can offer to "for go" the child support he would owe you in favor of he not having any overnight visitation for the first 2 years. If your baby doesn't take ANY formula, you will VERY likely win this if it goes to court, but... If he takes even 4oz of forumla a day, he will probably suceed in 50/50 custody. If it is decided that it will be 50/50, I sugest going with a 3 day-3 day or a 4 day-4 day rotation. This allows for him to have sability from the aspect of not being CONSTANTLY jugled.
My friend got hosed in her custody, because she had a job that gave her T,W,TH off so the judge gave the father M,F,S. and every other Sundy. The part that sucks is she worked at a bank, so every Monday holiday that she had off, he got the baby, and then she still need to have a babysitter on one of the other days she normally had off. She also NEVER gets her for Saturday, which is when most of her family parties are. She also HATES the that on her Sundays- She has the baby (just turned 3y) on Thursday, Dad Friday & Saturday, her Sunday, Dad Monday, her Tuesday. She feels like her daughter doesn't know if she's coming or going.
Also, if you go to mediation, I would request that holidays AND his birthday rotate- REGAUDLESS of who's "day" it is. My friend wanted to rotate it from their 2nd mediation and he said "No! A day is a day!" Well, this year Easter, 4th of July, their daughters b-day, Thanksgiving, Christmas, and New years day ALL fall on her time, so suddenly- he wants to change it, and she says "Maybe next year!" (When she'd only get Thanksgiving and Christmas.)
If you want other things she WISHES she'd have requested in the agreement, pm me and I'll try to give you more.
I hope it works out for you! I hate seeing how hard it is on the parents AND the children. ~J.
