Thanks for the encouragement readers have left me.
Finally bought my air tickets back to Singapore =)
I'm going back this coming weekend with my kids, but without my husband. Yes, I'm bring the twin back alone!
My friends & family were worried that I can't handle, but I believe should not be any problem. Coz Angela & Belinda is big enough to listen to my instructions. I have tried bring shopping myself before, it turns out ok.
Well, will update on my flight experience with them soon. =)
