Whether or not you can eat during labor depends on your circumstances and your healthcare provider's recommendations.
If you’re having a low-risk labor and aren't planning on having an epidural or a C-section, you might be allowed to eat light snacks. However, many hospitals restrict food intake during labor to reduce the risk of aspiration (inhaling your food and potentially choking on it) in case anesthesia is needed, like if you need an emergency C-section. Light snacks like toast or fruit might be allowed early on, but it's always best to check with your provider.
Staying hydrated with clear fluids is usually encouraged1 since it’ll help keep your energy up without the risks associated with a full stomach.
