Son sleeping in his own room first night!

This is the first night my son is sleeping in his own bed in his own room and I'm a nervous wreck. I keep checking on him and cant even think about sleeping myself (its 1:45am here). Did anyone else feel super nervous the first time their LO slept in their own room? I'm scared he'll wake up and I'll not hear him or he'll get too hot or something. Is it normal to feel so anxious about this? He's 21 months and has slept in my bed since 14 months (we went on holiday and RUINED his sleep), he's perfectly happy to sleep in his own bed. I guess I wanted him to fight it more so I could get my baby hugs a bit longer 😭...
