Pregnancy myth that makes no sense

Here's some that I have heard: 1. Don't eat crab, baby will come out sideways 2. cannot eat squid, because he will get sucked back inside 3. cannot eat chin chow, baby will become black 4. eat eau huay, so baby will be white 5. cannot hold scissors, baby will be in danger 6. don't do renovation, or home improvement, baby will have pock marks like hammering nails in their skin 7. Don't drink coffee, baby come out skin black 8 Cannot paste posters else baby come out eyes will take longer to open. 9. Cannot do sewing else baby won't cry/make noise. 10. Cannot carry another child when you are pregnant or else your own child would feel jealous
