It can be hard, but you do have to learn to let certain things go a bit longer than normal. My house, right now, is a total disaster from the holidays and us being away. It is driving me insane, but I am taking it one room at a time to try and get some order back. This is a tip that I have gotten from other working moms, do one room at a time, then you aren't having to do it all at once and you have more time each night with Ava. I am trying to work that out, still haven't gotten used to it and my oldest is almost 4
You will miss her, but that is normal, you will get through it and just try to tell yourself that it is just temporary. I have worked FT (40+ hours) since my oldest was 7 weeks and then with #2 I was lucky enough to get 12 weeks with her before having to return.
