I know there's prob alot of bubs out there that have gone into a bed this early, but think about him getting out and playing at night, unsupervised so able to hurt himself

I honestly think that depends on the child. Most children searching for their mum or dad at night as they are scared BUt that's if they do wake up

Only you know Ash if A is ready for a bed..and as I just re-read its a toddler bed.
if you are worried about him 'playing' at night..then make sure their is no light on in his room.
