POOJA KOTHARIMom of a 8 yr 5 m old boy4 months agoA. A 3-month-old baby weighing 5800 grams (5.8 kg) is generally within the healthy range, depending on the baby's birth weight and growth pattern. On average, a full-term baby is expected to double their birth weight by around 5 to 6 months. If your baby was born at a normal weight and is steadily gaining weight, feeding well (whether breastfed or formula-fed), passing urine regularly, and is active and alert, then 5.8 kg at 3 months is usually considered normal. Every baby grows at their own pace, and slight variations are common. However, if you feel that your baby is not feeding well, is unusually sleepy, or not gaining weight steadily, it's always good to consult your pediatrician for personalized advice and to monitor the baby's growth using a growth chart.
