Ang 4.7kg at 3 months and 21 days sounds healthy para sa EBF baby, pero mas maayos kung i-check mo na lang yan sa pediatrician nyo para sa peace of mind, especially para makita kung consistent ang weight gain niya month to month! A few of my mum friends were also worried about their babies' weight at that age, pero the doc assured them na basta kumukuha ng milk consistently at may wet diapers, okay lang, pero official check-up talaga ang best way to be sure.
