Bath - there already is a full sized single bed in the room and he absolutely hates it with a passion

Ive found a toddler bed for him on ebay - but it out for $95 with a mattress so the inlaws are bring it tomorrow. Its white like his cot so he should be alright with it and has safety sides on it also

I worry about him hitting his head. Ive seen him have enough fits to last me a life time.

thanks everyone for their input
