How long does it take for a newborn to lift their head on their own?

Patient's question:

No

Doctor's answer:

1-month-old baby, when prone, can only lift the head slightly and it soon droops again; when supported in a seated position, the head hangs low.
At 2-3 months, when prone, the baby starts to lift the head, forming a 45-degree angle with the bed surface; when supported in a seated position, the head can sway and stand upright for a moment.
A baby over 3 months old, when prone, can lift the head to a 90-degree angle, with more stable head lifting; when supported in a seated position, the head leans forward, but it stands upright stably.
