R.,
I've thought a lot about your wording, and, although I know I am not about to make any new friends here...here it goes...
Poor baby. Imagine being cared for by stranger(s) all day then finally coming home to parents fighting over who has to take care of me. :(
Poor husband. He comes home from a long day at work (just like you're about to) and wife feels like he's uninvolved with his daughter. He's worked and brought home an income so you could have these precious 4 months with your daughter, and now he plans to get her ready, take her to daycare, and pick her up and watch her until you get home - I think that's pretty involved.
Your baby isn't another item to add to a chore list that you split with your husband. She is a living, breathing, human who is growing everyday. She is your greatest accomplishment. She deserves so much more. If your biggest fear is having to hold her and care for her the instant you come through the door, then that doesn't make me feel sorry for you, but for your baby.
I've been in your shoes, so please don't think I'm on a soap box with no knowledge of your situation. I'll tell you that it was hard. Here are some things that I did to make sure that my selfish need for "me" time wasn't at other's expense:
1)treat your commute home as your "down" time
2)put your family on a great evening routine: dinner together, play time for everyone - tummy time together or a walk in the neighborhood, bath and bed for baby, special time with hubby, then all the you time you can handle. Remember that now that you're going back to work, the hours that you have in a day to impact your daughter's life have been dramatically cut - make every waking second count first, then you can take care of you have she's asleep. FYI-our kids' bedtimes have always been 8:00 for this reason. After 8:00 is mommy and daddy's special time for each other and for ourselves.
3) change your thinking. When you catch yourself thinking "I hope he doesn't hand her to me right away" or "OMG, one more person who wants something from me today" or "I'm so tired, I just need a break" replace those thoughts with positive, perspective-providing statements like, "I can't wait to see her darling smile! I've missed her." or "Thank You Lord for giving me a great husband and baby who need me" "This little person is the most important someone who wants something from me!" "Some drooly-giggles will really melt away a totally sucky day right now!"
I hope you don't think I've been to hard on you that you don't take my advice to heart. She really deserves more. Split the chores, share the baby! You'll miss so much during the day, don't waste what you do get with her. Being a mommy does require us to give up so much, but what we get in return is much better! :)
