Dh and I going to a wedding abroad. We'll be away 3 nights. The 3 DC's are going to be split
as no one can cope with all 3. They will be together during the day at the childminders, and going to sleep with different rellies. Dc1,6yrs, will be fine. Dc3, 2 yrs, will also be fine, but I fear dc2 ,4yrs, may never forgive us!
He is quite clingy, and going through a very angry stage anyway. He hates being left, even for an afternoon. He hates it if I go out and leave him with dh. He thinks I am his! He gets very jealous of his siblings. He is my cross, needy, emotional, intelligent middle child. He worries, eg death, pets dying.... Sigh. He reminds me of me.
So would it be better to prepare him thoroughly well in advance of the trip, so we can talk it through? Even though this will give him time to worry and fret? and rant and rave and hit and bite me or should we just go with little warning so he doesn't have time to think about it? Tbh I'm worrying so much about him I don't even think I'm going to enjoy the trip myself! He's the early riser, the night waker, the bed wetter, he needs his mum! 
Worse things happen at sea. He will be with a very nice aunt, uncle and cousins. I am going to give them each a new night light(of course he is afraid of the dark) .
How can I handle this so that he doesn't still resent me when he's 30?!
