I've 3 kids.我是1年1個的,頭2個已讀小學.當年我也是這樣,不過到最後都是自己湊返學放學,如果真是辛苦咪全日law,he still young .u can explain to him ,he can understand your situiation.or u give try 半學期睇佢情緒開不心開,咪知law.don't think too much.relax
If me, I will let the big boy go for the whole day kinder.
I think it is good for both of you even you little one. Like me, when my daughter is 2 years old, she already went to the whole day kinder. She is more independent.
You will be more relax and not get any trouble between the two kids.
