It is not mandatory to feed a baby every 2 hours; instead, you should follow your baby's cues for hunger. Babies have varying feeding patterns, and it is important to respond to their needs. To assess if your baby has had sufficient milk during breastfeeding, look for signs such as active sucking, swallowing sounds, relaxed body posture, and contentment after feeding. Additionally, monitoring your baby's weight gain and wet diaper count can provide further assurance of adequate milk intake. If you have concerns about your baby's feeding or milk supply, consult with a lactation consultant or healthcare provider for personalized guidance.
