can go for a short trip, to Bintan/Batam, 2D1N over the weekend?
As for the naming by the "shifu". I'm not baptised yet (preparing though), but my hb is a Catholic. It was mentioned at the church class by the priest that as Christians, we can only believe in GOD and no one (nothing) else, that inclds feng shui, astrology, fortune telling, etc.. So, I guess that this wld fall under this category. Since, bb belongs to hb and you, and hb is free-thinker (as of now), then your religion wld dominate. But, then again, it's a very sensitive issue if your MIL is insistent. Don't let this put a future strain between you and your PIL, coz if they're the insistent type, might end up nagging abt this for the rest of bb's life. Maybe have to discuss with hb and see how he feels abt it. Plus, also depends on how insistent they are. If it matters a lot to them, then it will be tough. Then, maybe have to give & take loh & adopt cel cel's approach, since they usually feel that grandchild belongs to them too, since it's their son's child.
Like SSF, I also have a cousin who followed her PIL's instruction and checked the name, even though she's Christian, but her hb is not lah and in fact, is those very superstitious type. For us, my mum also suggested checking the name with the "shifu". Who knows, maybe MIL will say so too, but my hb will deal with her. We plan to say no loh, since we're recently told that it's not right. But, my case is easier. I'll just say that it's against our religious teachings loh since my parents are aware of us being Christians.

Am going for 3D2N, but, minus travelling time, etc, seems like only 2 full days.

Don't worry too much, maybe your gynae just wants to play safe. Take care & update us again.
