I didnt really enjoy my ML. Felt incredibly bad about that - it wasnt that I didnt enjoy being with my DD, but I just felt a bit directionless. Pre-DD I had a very demanding, time consuming job and didnt really spend much time at home. Being in the house all the time felt very restrictive. I was also lonely. I didnt join any post-natal/baby groups because its not my thing at all (I did try, but not for me). My job has always been such a significant part of my life it was hard to function without it.
To keep my sanity, I went for a walk every day, no matter what. Even if it was just to the shop for milk. Get out of the house. As someone else said, set yourself targets but give yourself generous deadlines. Life was much better when DD and I found her routine and it gave me structure and opportunity to get things done.
My ML made me realise that being at home long term was not for me (something I had suspected pre-DD but this confirmed it). Now I am back at work, I relish time at home but I am much happier.
