At what age did your baby start using pillows and duvet?

Not until he was about 2.5 I would say. We did it when I converted his cot into a cot bed, when he trying to climb out!
So took the side off, and introduced a duvet and pillow

Just before their first birthdays ☺️

Actually not 2.5, it was just over 2 I think

When he was 2.5 and in a toddler bed
Until then he was in a sleep sack and cot and never tried to climb out
We only moved him as needed cot for baby

I didn’t get my LO one till a few months before her second birthday. I got her one of the mama&papa duvets so didn’t have a cover as I heard some horror stories 😭 she then got a pillow and ‘proper’ duvet at 23 months as she then had a Christmas one ahahaha

All 3 kids had them since 1 year old, my youngest loves sleeping with his pillow and won't do without it now. I just tuck the end and one side of the duvet around the mattress so he can't pull it up over him in the night
