Then I realized, as others have said, that she would be not even 4, with some kids close to 5 and that is HUGE and would definitely put her at a disadvantage.
Plus, I find that at this age, they swing from being "grown up" to a toddler-ish behaviour quite regularly-not something that would be accepted at Kidsgi.
So what I did is I signed her up for the Forest Krippe 1 day a week, to give her something new and stimulating for her last yr at Krippe, plus we will start Swimclasses.
I think this will give the right balance of more stimulating activities, whilst at the same time, letting her be a "baby" for 1 more yr.
By the way: I would start preparing your child for the friends leaving, and also discuss at the Krippe how they plan to keep him interested and stimulated? We had this discussion and it was good to know that they are aware and have a plan.
Lastly: apart for my and others opinion, I really think you have close to zero chances of him being accepted early. One reason is he is out of the special cutoff (May-June-July) and the second reason is it is way too late as the classes have been made already. You would also need to sign him off krippe or pay the 3 months notice period. (I know the monetary is not what is driving you but just mentioning the process)
Cheers,
