Aww, congratulations on your 4-month-old! But akak kena tanya, baby apa yang nak tanya normal ke? Like is it about poop, sleeping, feeding, or something else? Describe a bit more so I can share what my mum friends and I noticed with our babies at that age! If it's something yang looks urgent or you're worried, better check with your paediatrician ya, even just a quick call.
