Berat badan bby tak naik bnyak usia 4 bulan😌

Aiii mama, jangan worry dulu, 5.45kg at 4 months is still within normal range ok, even if it's on the lower side! A few of us mum friends went through the same thing, and honestly, as long as baby active, alert, and poo-wee normal, usually it's fine je. Since you're doing mixed feeding (formula + BF), make sure baby is getting enough at each feed, sometimes kalau terlalu cepat switch feeds, baby tak sempat empty one breast properly, so dia tak dapat the richer hind milk yang helps with weight gain. Try feed on demand, and don't rush the BF session. If you're worried, best to check with your pediatrician or lactation consultant to see if latch is efficient or if need to adjust formula portions, because they can see baby's feeding pattern directly.
