Breastfeeding Guidelines: How Long Should You Breastfeed Your Baby?

WHO/UNICEF Recommendation (Global):

• Exclusive breastfeeding: First 6 months (no water, formula, solids).
• Continued breastfeeding: With appropriate complementary foods until 2 years or beyond.

AAP (US) Recommendation:

• Exclusive ~6 months.
• Continued with complementary foods until 2 years or longer as mutually desired (2022 update).

Benefits by Duration

• 0–6 mo: Optimal nutrition, passive immunity (sIgA, IgG), microbiome seeding, reduced infections (GI, respiratory, otitis), SIDS reduction.
• 6–24 mo: Continued immune protection, nutrition (29% energy, 43% protein, 75% vit A in 12–23 mo), neurodevelopment, maternal bonding.
• >24 mo: Ongoing immune/psychosocial benefits; no evidence of harm.

Maternal Benefits

• Reduced postpartum hemorrhage (oxytocin).
• Lactational amenorrhea (natural spacing if exclusive).
• Lower lifetime risk: breast/ovarian cancer, type 2 diabetes, hypertension, CVD.

Practical Notes

• Complementary foods at ~6 mo: iron-rich (meats, fortified cereals), varied textures.
• Weaning is gradual; follow child's cues.
• Support matters: lactation consultants, peer groups, workplace accommodations.

Any breastfeeding duration has value. "Fed is best" includes formula when needed – no guilt.
