I don't understand why the children are always accompanying Albert in official or semi official trips to other countries. I get the family has gone thru tough times, I get Monaco does its own thing and rarely follow any other type of royal protocol....but come on. Working foreign trips are not for children, like most of us won't take our children to working trips or important meetings. Even if Albert and Charlene don't want to part with them, they have plenty of support to take the twins with them but still kept out of the limelight.
I really think the kids are being over exposed and being centre staged in adult business. Personally, I don't like it.
I think the children are not yet ready to have the parents out of their sight. Charlene was missing for 1/7 th. of their life and she has been back only for 3 months or so. Gabriella constantly holds her hand and her brother is always near his father.
I mentioned before that my father was in the hospital for a long time when I was +/- 7 years, how scared I was that my mother also would disappear. My mother says I was very very 'clingy' for a long time after.
It is maybe no coincidence that this first trip is to one of the most relaxed royal families, and the events are day time and not state visit, if I am correct, so for me it's no big deal that the twins are included this time.
