I totally disagree, especially as she may need his help due to her long work hours. I have a friend who is only communicating with her ex by text about their kid at this point because she took a hard line (and chewed him out) too many times. You really have to keep in mind that you'll be co-parenting for at least the next 15 years. Think about this: do you want to not be invited to your kids wedding because you couldn't get along with their father?But I would definitely send an email noting that this violates the agreement (and stating how) but that you won't force him to change the tickets this time, as long as he won't do it again and lets you make up the time over the 4th.
As for the other incident, if anything something like that happens again, OP, you need to make him fix the problem he caused (in that instance, find and pay for a sitter). Make it a very matter of fact, non-emotional conversation.
are you OP's husband by chance? in less than a month he has already violated the agreement twice, and once booking an 11 day trip taking away Easter and OP's week end with the kids with no permission, and she should let go? how do you think he is going to behave in the future if he think he can get away with this behavior? this does not look to me like a normal adjustment period with an overreactive ex wife chewing the ex husband off for no reason. it looks more like an abuse ex trying to walk over the former wife. it is only going to get worse if she does not set things straight. and I more inclined to bet that the ex husband will be the one not invited to the kids' weddings
