He sends 2 nights a week with eldest who is 5. Youngest doesn't sleep overnight, he's 1.
Whilst he sends 2 nights a week with them and that sounds a lot, in this time is school and then dropped off at school so the 121 time is not as it seems.
He wants to take them abroad and I don't feel comfortable.
At what age would be reasonable for ex to take children abroad?
It's a sensitive matter so don't come for me in the replies.
