I've name-changed here.
ExP and NP want to take DS on holiday. He's just turned 3, never been on holiday before. DS is usually with his dad 2 nights a week. I think a week is enough and longer not in DS's interests. They are threatening, hassling, pushing for me to agree to 10 days because that's what would suit them as a family (NP has other older DC's) and I am potentially ruining this.
I know its only 3 days more, but I really feel a week is long enough on this first occasion.
I'm being threatened with lawyers - what can I/he do?
Any ideas/advice? Thanks folks.
