Aiyo, babies do have their own sleep schedule in the womb lah, so it's actually quite normal for yours to be more active at night, a lot of mum friends I know experienced the same thing! But 12 morning before any movement is quite a long stretch, so I'd suggest checking with your doctor just to be safe, especially at 33 weeks when they're monitoring movements closely, better safe than sorry kan. Meanwhile, try tracking the kicks more consistently to see if there's really a pattern, and let your gynae know next visit; sometimes babies just prefer their quiet mornings and party times at night (yang annoying kan when you're trying to sleep ).
