My kid is sleeping in a big boy bed for the first time tonight

He'll be 2 years old in May, but he's nearly outgrown his travel cot we've been using for a long time. He's having his first night in a toddler bed (smaller than a single and has a bar halfway down one side to stop accidental rolling out).

He's had a bit of an overwhelming evening figuring out the new configuration, and had to have his dad come and comfort him and tuck him in (literally to stop him getting up again!) But he's been asleep since then.

Quite emotional, a bit apprehensive about the rest of the night and following sleeps over the next few days (how will he find napping in it?) but also so impressed with him.
