DD is 5 months now and I cry at anything! I don't seem to cry at nothing if you see what I mean, but for instance, when I put her to bed and she smiles I say to her that I love her and I nearly always have a little cry.
Even when I watch TV and something is remotely sad I cry. Thinking of anything even remotely emotional and i'm off. 
I don't feel that i'm not coping or anything, I just seem to be very emotional. I don't think for one moment I have PND, I just wandered if others are the same and how long it might last for.
TIA
