Pusod Not Yet Fallen Off

Hi. Im so worried. 28days old na si baby. Hindi pa rin natatangal yung pusod nia. Wala namang amoy or sugat or any sign of infection. What should i do? Update: 1month and 9days old na si baby. Hindi pa rin natatangal yung stump pusod nia. Huhuhu. During his 1month checkup.. Ang sabi lng ng pedia continue applying alcohol.. Bakit antagal matanggal nung kanya? Matagal matuyo yung nasa loob na dugtungan. Every diaper change and bath time nmn nmin nilalagyan ng alcohol.
