I got divorced many years ago . . . we had joint custody, but in our lives, that meant I had custody, and Dad wasn't around much. So my advice may be tempered by that.
For starters, I think you have to realize that the kids will be hurt some. But they also carry the hurts that their parents didn't get along. And so do you. Divorce is a method of giving unhealthy families a chance to heal and become healthy. And it sounds to me as if being healthy is very important to you, esp when it comes to your children. A+ for you !
The best gift you (and he) can give your children is to be healthy adults, and then from there, to help them to grow healthy.
Even though they are young, they know Mommy and Daddy are stressed, and they know this is a difficult time. You don't have to give profound explanations to them, but you need to be sure to explain that you two are getting divorced, and that while you are no longer committed to loving each other, that you both are TOTALLY COMMITTED to loving them and taking care of them. Invariably, it will be difficult for them to get used to swapping parents on a regular basis, but kids are very capable of dealing with change, if we help them through it. Transition days will be kind of tough for a while, but let them voice their concerns and frustrations, however they come out, verbally, or non-verbally, and they will know they are accepted, and it's okay to feel the way they feel. By acknowledging how they feel, you are letting them know they are okay, and normal, and that you understand. the more you and they are able to talk about it, the easier it will be for them as they grow, to turn to you guys to talk about the big issues in their lives, and their friends lives.
As you decide on the custody arrangements, try to think through not just what will work for now, but what will work 3 to 5 years from now. For instance, whoever gets both Friday and Saturday nights may not mind being tied down on weekends right now, when everything is fresh, but when that person starts dating, Friday and Saturday nights with children mean babysitting costs, and/or leaving the children with the other parent, which might be difficult to do without making the children feel unwanted, or as if they are an inconvenience.
this can work really well, especially if you both stay in the same town until the kids have grown up. But you need to discuss that option as well, because what happens if one of your careers asks you to move 100 miles away ? Who gets the kids then ??? or, one of you is re-marrying, and the new spouse gets a promotion that requires a move ?
Obviously not all of this needs to be decided now, but it's good to think some of that through and think about whether or not you could sanely discuss these issues with your ex 5 to 7 years down the road . . . .
Whatever custody arrangement you have, try as much as possible to keep the communication open between yourself and your ex, as well as with your children. It's really important, cuz so often the kids will share stories that make you angry with the other parent -- and the stories may not be fully true. You need to be able to call and ask, rather than jump to conclusions. and you need a high level of trust in each other's child rearing skills to work with different households/different rules and expectations, for the next 15 years.
Also to think about: Do you go to dr. appointments together? Who is responsible for healthy child visits --medical and dental ?
My divorced girls are now 27 adn 24. We had some really difficult years -- esp after I remarried, and then definately after he did, because his wife didn't like the kids, so he quit seeing them. My husband and I had a lot of anger to listen to, and deal with, but you know what ? Both girls are healthy young adults, with exciting careers, and I am just busting with pride. They have been through a whole lot, but they have survived, and they succeeded. Yours will, too. I hear it in your love for them !!
