Oh darls You are completely normal and not failing at all. It is such a huge change with so many emotions and not many people can cope with zero sleep without some feeling of resentment and tiredness I found my baby blues (not PND) hit at around the 2 week mark because the warm glow of what we had made wore off and the sleeplessness kicked in. What worked for us was getting a hammock. He was cocooned and actually slept in it instead of on us. He hated his bassinette even if we tried propping him up a bit with towels etc. He had a wee bit of reflux. I would be super worried about sleeping with him on you like that babe. We did it too and I would wake up terrified that I had dropped him (or that DH had dropped him or smothered him in his sleep). I would be looking at ways that you can try to settle him. Completely normal, do not beat yourself up for feeling resentful of the crying, you are resenting not having sleep because of the lack of sleep not resenting having a baby at all if that makes sense. Slight difference but a big one. xoxox

ETA: Do you have any support around you? Can someone come and watch him during the day so you can rest? Is your DH home right now - can you take it in turns at night? Try and get some fresh air each day if you can, if someone comes over go for a 10 min walk ALONE. It is really important that you take some time out even if it is to have a long hot shower
