Unsure what to do with myself...

Normally at 11:30pm I am fast asleep after an exhausting day. Tonight I am wide eyed and bushy tailed. Today I put my son down for a real nap in his own room in his own cot and he slept for one whole hour! Tonight I have put my son to bed at 8:30 compared to the 10pm and beyond time that he normally goes. I'm still in shock that he's asleep! I know I should be sleeping but I feel unstoppable. I'm gonna regret saying this but I think I'm getting this whole mummy thing down! 👍🏻
