There are several signs that can indicate that your newborn baby is full:

• Slowing down or stopping sucking: During feeding, your baby may start to slow down or stop sucking altogether. This can be a sign that they have had enough milk or formula.
• Relaxed body: A content and satisfied baby may have a relaxed body posture, with their arms and legs resting comfortably rather than being tense or fidgety.

• Releasing the breast or bottle: If you are breastfeeding, your baby may release the breast on their own when they are full. Similarly, if you are bottle-feeding, they may turn their head away from the bottle or refuse to take more milk.
• Turning away: Your baby may turn their head away from the breast or bottle or show disinterest in feeding when they are full.
• Spitting up or dribbling milk: Some babies may spit up or dribble milk from their mouths when they have had enough to eat. This can be a natural way for them to regulate their intake.
• Contentment after feeding: After a feeding session, your baby may appear content and satisfied, perhaps even falling asleep peacefully.

It’s essential to learn your baby’s hunger and fullness cues and respond to them accordingly. Offer the breast or bottle when your baby shows signs of hunger, and stop feeding when they indicate that they are full. Overfeeding can lead to discomfort, spitting up, or excessive weight gain, so it’s crucial to pay attention to your baby’s cues and feed them responsively. If you have any concerns about your baby’s feeding habits or growth, consult with your pediatrician for guidance and support.
