Thanks, utopian! I wad your post about the baby blues and mourning the loss of your old relationship with your husband (although you phrased it differently) and immediately told my husband about it, as I had exactly the same reaction. On the first day, I was in floods if years about how much I lived him, on the second I was more low and anxious, and missed him madly though he was sat next to me! I agree with your partner - do let it out (I found some good sobs very helpful) and keep talking about how it feels. You'll then both be able to work our if it turns into something more than baby blues. I also found it helpful to tell my husband to quietly mention the blues to guests if need be - I also found talking about the people at the birth (consultant, anaesthetist) hugely emotional. That way, I knew guests would understand if I burst into tears.
With grassiness (stupid autocorrect) we have been using infacol. I got a bit complacent about whether we needed it and skipped some doses (plus have been gassy myself) and little C has been waking herself up with pain. She doesn't burp much after feeds, just struggles to poo and fart. We're getting better at massaging them out of her 
but now we are going to give the bottle occasionally will also try Colief. Poor wee mite.
