vinette: i bought from ASOS maternity. bought one size up then i'm regretting it a little cos its looking a little baggy on me. so i would say just get your usual size. but... depends on your weight gain also la, i have gained 2kg so far and tummy like barely there... its baggy both at the waist and at the chest area. theres one that looks super baggy on me, so i'm saving for when my tummy is bigger, then at least wont look so weird.
ellen: i guess then it depends on their motivation lor. that can only check during interview bah. i know my colleague's maid from indon, she has 2 kids, then her husband useless, only know how to take money, and got another woman outside, so she works quite hard to provide for her family. her kids are taken care of by another auntie in the village. then she's working hard to buy house for them and provide them w proper education etc. she misses her kids la, but she loves my colleague's young kid too and takes good care of her. well.. this maids thing really depends on luck.
anyway, health and baby more important la. else check if there's flexibility for you to do some work from home. at least not so taxing.
