Hello!
Our Kindergarten does this too - they go on Friday!
My PFB went 3 years ago - youngest in her year and was still 5 (5 years 8 months), and PSB :o ...DC2 is going this year if he gets over the weird bug he has by then age 6 years 8 months (3rd oldest in his year).
Oddly I wasn't ridiculously worried about DD - she didn't have any concerns about going, had very strong social skills and had who to share a room with all sorted months before she went, looked forward to it hugely, enjoyed it massively, everyone in her intake went (small village - they all go from the one KiGa to the one school together, one class intake) and it was a very important bonding experience which they still refer back to today. She has a strong circle of friends, all but one of whom she was at KiGa with...
DC2 is a different kettle of fish, and has been very worried about it (waking at night having nightmares about it) but I have been building him up to it as I think its important he goes - he did an overnighter with Oma and Opa (luckily DH is German and they live an hour away) which he didn't want to do, but we eased him into by staying there a night too and then leaving him with his siblings the next night - he used to stay with them sometimes as a toddler (with his sister) but had been refusing to in recent years and we had let him stay with us while his older sister and younger brother stayed. DC2 has a more mixed bag of friends, mainly based around his football team and neighbour kids, a lot are older and already at school, and equally he plays with younger kids - so his peer group, unlike DD's, are not so clearly the ones going on the trip, and he is worried about who he will share a room with. Infuriatingly the boy he is closest to in his intake year is not going - DS's friend thinks for money reasons (the trip is €95), although his teacher told me it is his mum's separation anxiety :o
Anyway stupidly I am more worried 2nd time around, due to DC2's character, BUT I know (from DD's experience) that he will have a brilliant time once he is there.
His KiGa have been brilliant (they are fantasic anyway, love our KiGa) at allaying his fears and even had a "meeting" with him (with me present, in the staff room like a "grown up" meeting) where he could ask all his rather thoughtful insigtful - and bat crazy :o - questions. Since that and the over night at Oma's we are both less worried, but he still has a wobble about once a day, and I am dreading getting him out of our door to KiGa and on the bus on the morning...
What I am saying is... I've done it and DD had a great time, and I am so convinced it is overall a good thing that I am really working on selling it to my much more anxious and less enthusiastic DC2 as I think he will get so much out of it, if we can just get him to go in the first place and I've already paid -:o
How, crucially, does your DD feel about it?
