Enne,
getting a maid is a good idea, but also bear in mind it takes a while for Lego to adapt to maid, and also your MIL to adapt to maid. BUT, at least with a maid, Lego is at home, so i think won't cry as compared to going to CC. go CC, is really almost confirm will cry. of course there are some kids who don't but that is the rare type.
You will need to have some adjustment. But seriously, having a maid is good help, especially since your MIL is at home to supervise. Then maybe every night, you can bring maid and Lego home, while leaving small L there first. Slowly, as small L gets better, then u can bring all home every night.
So in a way, your MIL won't feel too much intrusion, since u bring the maid home.. but in the day, she has help with both Big/small L.
Let me know if u really want to consider maid. I will call and talk to the agent for u ok. Cos last time i very stress about finding maid.. i so emo until i nearly cried out in the agency.. my agent see me so worried, also feel bad for me.. then she can find this good maid for me.. i feel is also yuan2 fen4 and luck.
