besides I know I can go where ever i want but I want to take my kids with me I'm still breastfeeding. My question is how can I take my kids with me.
Legally? Well technically, you can take the kids out of state. Just expect a court to order you to return the children to the state when Dad gets this into court. Of course, then you will have to return them and go to court providing Dad with every bit of evidence he needs to show the court that you think nothing of hi-jacking his relationship with his children. The children will remain in CA and very likely in his custody while you exercise visitation. Luckily, in this scenario, as you wish to move out of state, it should be physically easier on the kids for YOU to go back and forth instead of them.
Do you really expect everyone to believe that there is not one place for you to live in the whole state of CA?
Breastfeeding is not a legal excuse to deny Dad any time or inclusion with his children. That's why bottles and breastpumps were invented. Horrors...if worse came to worse, there's a wide variety of baby formula that will do in a pinch.
