I live with my mother.
However, my case is difference with yours.
我地(my husband and I)係兩個人住 before.
After having my kid, we employ a bun bun.
In the begining, my mother came to 'look after' my new born kid frequently (and back to her flat at night).
Then, I gave her a room and ask her to stay overnight (so that she didn't need to come daily....).
Now, most of time, my mother lives in my flat. => i.e. we live together!
P.S. My mother bought her flat.
Sometimes, if my son/husband make her angry, she will back to her flat for a few days!
I wonder why too... My mum will move in to stay with me and my husband, she will take care of bb for me ah... I hope it works la... but I can never imagine myself moving into my 6299's home loh, they are too farn la.
