I hope it goes without saying that I absolutely adore DD (10w) and that she is the most amazing thing that has ever happened to me and that I can't quite believe how lucky I am.
But today I went round to our old house where we lived before she was born (we are selling it) and was totally overcome with a wave of sadness about my old life in that house, and my old life before her. All our furniture and stuff is still there and it just felt like another life that I will never have back again. I have been feeling this for a while but going to the house made it very clear.
I sat in the car afterwards and cried which I do know is pathetic,
as I am so lucky to have DD and the whole reason I wanted a baby is because I knew there was more to life than the things I did before!!
DH and I waited years and years before even trying as we were very happy with our lives as they were; so I always knew I would miss aspects of it when we had a baby but even I didn't realise how much.
That said I did not also realise just how much I would love DD, so I really knew nothing!! 
Part of the problem with waiting so long to do this is that we were very settled and content with each other and I really 'miss' DH now as we never get to talk anymore; life is a whirl of nappies and milk and all the stuff that comes with a new baby.
I miss the old me too and I miss my work... I miss not always having someone else to be responsible for, incredible a privilege though it is to have her.
I had a lot of problems in my 20s and it took a long time for me to build a life that I was happy with which is why I appreciated it so much; I just miss it, that's all.
AIBU or has anyone else felt this way? If so does it fade with time?
Stupidly however we are being offered an evening of babysitting from the grandparents so I COULD go out and have a meal with DH and chat a little bit like the old days but I can't (aka won't) leave DD!!! Which is just ridiculous. Please tell me that gets better???! Will I ever feel it is OK to leave her at any point in the next 18 years...??
