is normal. i was also very 'tam jiak' during pregnancy (except the period when i had MS). i can eat a normal serving of main meal after that have waffle, bread, biscuits, titbits etc etc. not very hungry but just feel lik eating. that's y that time my mum and hub will always stock up snacks at hm and buy many foods cos they know someone (me) at hm will help to finish. LOL! for me, i just follow my cravings so if i cant getto eat what i craved i will become very 'cranky'. haha!
