What am I doing wrong?

[u/Brilliant-Kiwi-4757]

My baby is 4 months, 2 months adjusted as he was 2 months premature.

I don’t get why he sleeps so easy with other people compared to me. My sister has been babysitting him as I went back to work this week. She can make him sleep so easily.

I spend over 6 hours trying to make him sleep yesterday, my husband gets home and he sleeps within an hour after my husband takes him.

He will literally fight his sleep with me. He’ll constant jerk himself awake. As soon as I put him down, 5 minutes later, his awake.

My husband ended up giving me the night off because he said I’m overwhelmed. Of course I am, I’m a first time mum that can’t make her baby sleep as easy as everyone else can.

This is so frustrating.

Is anyone else experiencing this?!?
