Check that the cot mattress fits without gaps
Use only a correctly sized, firm, flat cot mattress that fits snugly on every side, and recheck it after making the bed.

Why it matters
A gap can trap a baby's head, face, or limb, while a soft surface can obstruct breathing.
Wrong action
Use an undersized, soft, or displaced mattress that leaves a gap beside the cot.
Correct action
Use only a correctly sized, firm, flat mattress that fits snugly against every cot side.
What to do
- Remove pillows, pads, and loose bedding so the full mattress and cot edges are visible.
- Press along every edge to confirm the mattress is firm, flat, correctly sized, and snug against the cot.
- After fitting the sheet, inspect all sides again; stop using it and tell the employer if it shifts, sags, or leaves a gap.
If something happens
If an infant is trapped, breathing abnormally, or unresponsive, remove the danger and call 999 immediately.
