Can You Eat Leftovers When Breastfeeding?
Written by Jordan Morley · Reviewed against NHS: food and drinks to avoid when breastfeeding · Last updated 28 October 2026
Yes. Leftovers are fine while breastfeeding if they were chilled within 1–2 hours and are eaten within 2 days, and reheated until steaming hot all the way through.
What the guidance says
There's no breastfeeding rule about leftovers. The general NHS and FSA food safety rules apply: cool quickly, store in the fridge, eat within 2 days, reheat once until steaming hot, and treat rice with extra care.

Common questions
Is leftovers safe while breastfeeding?
Yes. Leftovers are fine while breastfeeding if they were chilled within 1–2 hours and are eaten within 2 days, and reheated until steaming hot all the way through.
How long can leftovers stay in the fridge?
Up to 2 days (NHS/FSA). Freeze anything you won't eat in that time.
Can I reheat leftovers twice?
Reheat once only, until steaming hot all the way through.
Was this different during pregnancy?
In pregnancy our verdict was “fine if chilled promptly & reheated once” (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.
