Fight the missing my baby holiday bludes by spending some time with someone that may be lonely, a senior citizens at a nursing home, children at the hospital, homeless/battered women's shelter or some one in hospice care. Take them a book, a deck of playing cards, or some lotion or bubble bath. If you like reading stories, you can read some stories to children or rock border babies (babies abandoned at the hospital by their mothers).
I find that when I am too busy feeling lonely or sad in my own situation, doing something especially nice for someone else always makes me feel better.
An alternative to this is spending some quality time to yourself for yourself. Have a spa experience in your own home or invite some friends over to hang out with and play games or cook a meal together (ask everyone to bring one thing - you use those things to make the meal). Exercise, movies, reading a great book, listening to some upbeat music while dancing with wild abandon are some other things you can do to get your mind to another place. It is fortunate your little girl is loved and cared for by many. It is important for her development to not see you lamenting over her absence. My son is always torn between me and his father with the same thing but I encourage him to have a great relationship with his father and I rry not to make him feel guilty about being with his father and family for the holidays. I just find other things I can do and do that instead of "feeling" sorry for myself. I count my blessings. Hope this helps even though it is days later.
