Son sleeps fine with my wife, never with me

Heya, hope I can get some advice, I feel like a terrible father right now.I work a late shift, getting home around 2am, our son is 16 months old (3 months prem) and obviously he is well gone by then, he goes to bed at 7:30. So I am usually not here when he goes to bed.Tonight my wife is out with friends, but usually on a Saturday it's the two of us and he sleeps fine, but tonight, and on sundays when she works its just me. He wont sleep, at all. Last sunday it was gone 9pm when he finally went to sleep, then he was back up again at 3am.I don't do anything different, we have a play, he has his bottle with a story and I lay him down. Then he cries, and cries. After that he cries for a bit before having a good cry. He's normally an angel (when not got a tooth coming) but I really dread his bedtimes when I am home. via /r/Parenting http://ift.tt/2txYmw6
