My 8 week old will only sleep on me. Occasionally he'll sleep on DH. I've tried everything to get him to sleep somewhere other than me- or just be put down awake while I make a cuppa/have a pee etc.- a moses basket, a next to me crib, co sleeping next to me in bed, three different types of swings, a baby play gym, a sleep nest, a blanket on the floor. If I pop him in the pram and rock him to sleep he wakes up as soon as the motion stops. Same after a walk in the park. Will obviously sleep in the car but that doesn't help my sleep 
He just about tolerates his bouncy vibrate chair while I have a shower. I've tried feeding him to sleep lying down (ebf). Putting him down awake but drowsy, transferring him when he's deeply asleep. Nothing works! We can't carry on with him sleeping in my arms all night as it's not safe. My first DC could be put down to sleep anywhere so this has come as a bit of a shock. My eldest did have really bad reflux but this was managed using gaviscon. I wondered if silent reflux could be causing the issues maybe? As when sleeping on me he's not sleeping flat on his back and maybe that's the issue? Is there another trick I'm missing? Will he still be sleeping in my arms when he's a teenager? Help please!
