Eh, baby berak cair memang normal lah, especially kalau still exclusively breastfed, loose stools tu expected je sampai dia start solids. Tapi kena tengok berapa kali sehari and ada signs lain ke macam fever, lethargy, atau nappy rash yang teruk, kalau ada, better check with the doc just to be safe, sebab sometimes it's just digestion, but boleh jugak indicate gastro or infection.
