Common questions
Is prawns safe while breastfeeding?
Prawns — cooked or raw — no longer carry a pregnancy-specific risk once your baby is born, though thorough cooking remains the safest choice for everyone.
Was this different during pregnancy?
In pregnancy our verdict was “cooked — cold prawns need heating” (see our pregnancy guide for the reasons).
What should I avoid while breastfeeding?
The NHS list is short. Caffeine: try not to have more than 300mg a day (a mug of filter coffee is about 140mg, instant 100mg, tea 75mg). Alcohol: it is safer not to drink, but 1 or 2 units once or twice a week should be fine. Oily fish: no more than 2 portions a week. Shark, swordfish and marlin: no more than 1 portion a week. Peanuts are fine unless you're allergic. Most other foods that were off the menu in pregnancy, such as soft cheese, pâté, cured meat and runny eggs, are not restricted.
