When I was pregnant with my girl, I went through phases where I craved really sour stuff like asam laksa and green mango with rojak sauce, then suddenly switched to wanting McDonald's fries at odd hours. Cravings can be pretty all over the place and there is probably no rhyme or reason to it, but I think giving in to them occasionally is fine as long as you are watching your overall diet. My husband used to joke that he knew what I wanted before I did because the pattern was so predictable lah. Would love to hear what other mums here were craving too, it is always fun to compare notes.
