Baby is 3 months and 5 days old, unable to roll over or lift their head, what should I do?

Patient's question:

No

Doctor's answer:

Don't hurry, don't force the baby, this is all natural. If they can't explain it, it's not yet time; their abilities aren't enough yet. My baby is quite chubby, and he didn't lift his head well either. He didn't roll over until he was more than four months old. I was very anxious before, teaching and guiding him.
