Similar to you, I also 有抱 Hei Hei but cannot be a long time. Hei Hei likes to kiss my tummy to his brother. However, I don't really know if he understands what is brother. Perhaps after litttle bb born, he still kisses my tummy for his brother.
My doctor has increase $500 for operation. I think I will not join package this time.
Hei Hei will say "OR" when he need to VV or Ng Ng most of the time in the current 3 weeks. However, I still let him wear diapers as he sometime "wet" the diaper. I'm afraid he will be 線親 if not wearing diaper.
