Aiyoh don't worry lah, 2.1kg at 32 weeks is actually okay je, baby's on track and still have time to grow nicely before delivery, and doctors always monitor these things closely so if anything changes they'll tell you during your next checkups. A few of us mums in my circle juga had bigger babies predicted, but at the end of the day the doc will decide what's best for you and baby, so just follow their advice and maybe ask them during your next visit what they're watching out for and what signs to look for lah.
