Step 1: First tiny taste
Offer a small taste of smooth infant rye cereal or well-cooked mashed rye. Watch for concerning symptoms such as hives, swelling, vomiting, or breathing trouble, and seek urgent care if those occur.
Rye
Overview
Rye is a gluten-containing cereal and a Codex priority allergen. Rye can be introduced with other complementary foods around 6 months. Offer infant rye cereal or well-cooked mashable rye as a single new food. If your baby has severe eczema or a prior immediate food allergy, talk with a clinician before introducing highly allergenic foods.
Preparation
Offer rye as iron-fortified infant cereal mixed with breast milk, formula, or water until smooth, or as well-cooked mashable rye grains. Do not offer dry bread chunks to young infants. Do not put cereal in a bottle. Always supervise eating.
Three-step introduction
Step 2: Larger offer
If the first taste was tolerated, gradually offer a larger amount of the same preparation at a later feed.
Step 3: Include regularly
If tolerated, keep this food in the diet routinely as part of complementary feeding.
FAQ
When are babies usually ready for solid foods?
Complementary foods are typically introduced around 6 months of age, when the baby shows developmental readiness (for example, sitting with support, good head control, and swallowing food rather than pushing it out). Introducing solids before 4 months is not recommended.
When can rye be introduced?
Once your baby is ready for solid foods (typically around 6 months), rye can be introduced with other complementary foods. There is no evidence that delaying common allergens such as gluten-containing cereals prevents allergy.
How should I prepare rye for a baby?
Mix iron-fortified infant rye cereal with breast milk, formula, or water until smooth, or cook rye grains until very soft and mash them. Do not offer dry bread chunks to young infants. Do not put cereal in a bottle. Always supervise eating.
What if my baby has severe eczema or a prior food allergy?
If your baby has severe, persistent eczema or had an immediate allergic reaction to a food — especially a highly allergenic food — talk with your child’s pediatrician about how and when to introduce highly allergenic complementary foods such as rye.
