Dd was the same. To the point where i just made sure i was home so she could sleep there. So i have no solution really. Is he a little uncomfortable in the pram, i found it helped when i changed the straps so she didnt hsve them going over her shoulders so she could move about more And get into a better possition. I basically just had to accept that she wouldnt sleep in the pram. Sorry. Not what you wanted to hear im sure! Hope you have more luck!
